[[caption-width-right:350:"That terrible moment when you must make sense of '''who you are''' and '''what you did'''."]]

!Issue 3:
* Shock's mournful monologue to Ore's corpse was really touching, even if they were both just a bunch of throwaway guys. [[ShootTheShaggyDog And then the Sparkeater kills him]].

!Issue 6:
* Whirl, after being an axe-crazy sociopath who caused Megatron's StartOfDarkness and therefore ''[[NiceJobBreakingItHero is responsible for the entire Great War]]'' reveals that he was once a happy and successful watchmaker before the corrupt Senate drove him out of business, replacing his hands with bladed clamps to insure he'd never be able to do the job he loved ever again. Hardly condones his actions, really, but does go a long way to explaining them.
* Fort Max completely breaking down when Rewind shows him footage of his torture from Garrus-9.
-->'''Rung:''' Close your eyes, Max. Don't look. It's alright. It's okay. [[MeaningfulEcho We're done. No more for today]].

!Issue 7:
* In issue 7 it's lightly implied that Krok's squad is either dead or went on without him and he's just mentally blocked that out, assuming they're missing and constantly looking for them even though he'll never find them. That's pretty damn sad even for this series.
* A subtle one but when Chromedome meets with Brainstorm he comments that he's Brainstorm's OnlyFriend. And Brainstorm doesn't correct him...
* Red Alert saying goodbye to comatose Rung before his suicide attempt. The others make light of his paranoia, but it's not so funny when he's legitimately convinced not only that his superiors are going to kill him if he doesn't do himself in first, but that they orchestrated Rung's shooting because Red Alert told him about the voice. Made even worse later when it turns out that two of the three ship officers were in on the Overlord plot, so while they may not have had it out for Red Alert, his unwillingness to trust them isn't unfounded.

!Issue 11:
* TheReveal that the Senator who befriended Orion Pax, defied his fellow corrupt senators, modified Orion to carry the Matrix, and ultimately surrendered himself to save Orion [[spoiler:is ''Shockwave''. Shockwave's current state is due to the Senate brainwashing and mutilating him.]] There's something inherently tragic and ironic about the fact that [[spoiler:the two people who played the biggest role in making Orion into the heroic freedom-loving Optimus Prime, Megatron and Shockwave, became two of his worst foes.]]
* Rodimus takes it very hard when he learns that Red Alert actually committed suicide, or attempted to, than suffering an attempt on his life by Cyclonus. Rodimus has made some bad calls during his tenure as captain, but this scene hits home what a FatherToHisMen he's really trying to be, taking it hard that he didn't see how much strain Red was under, despite having taken the time to talk to him about how worried he and everyone else was about him. You know how hard he's taking it as a personal failure on his part when they agree to put Red into storage until such time as they actually are in a position to help him.
-->'''Rodimus''': See you later, Red. Promise.
** Gets even HarsherInHindsight: Rodimus ''was'' in on the whole [[spoiler:Overlord]] thing. This is more his responsibility than we knew at the time, and his guilt isn't just because he's upset Red Alert didn't trust him, but because he knows he was ''right'' not to.

!Issue 12:
* Just about everything pertaining to Chromedome and Rewind in issue 12.

!Issue 13:
* Tailgate coming clean to Cyclonus in issue 13 about lying about his entire backstory as a bomb disposal expert, a member of the Primal Vanguard, and crewmember on the Ark-1 because he's so frustrated that even after he went missing on the Mitteous Plateau-he was actually headed to the Ark to finish rinsing out its cooling chutes because he's a ''waste'' disposal 'bot-for six million years and no one ever noticed or cared, that he created this backstory so that someone might actually care about him. However, it turns into a [[SugarWiki/HeartwarmingMoments heartwarming moment]] soon after.
* There's another one for Swerve at the end of issue 13 as well. Since the start of the series, Swerve has mentioned on several occasions that he's best friends with Blurr and that the two of them planned to open a bar together after the war (which they've both managed to do independently, with Blurr reopening Maccadam's on Cybertron, and Swerve's bar on the ''Lost Light''). Issue 13 is Swerve sending a message to Blurr over his personal hailing frequency about the events on Hedonia, only for after ''nine hours'' of recording, Blaster tells him the transmission isn't going through. It's not going through because Swerve ISN'T friends with Blurr, and that they only actually met once, millions of years ago before the war at an autograph signing, and Swerve coming across as an obsessed StalkerWithACrush actually freaked Blurr out more than anything, causing him to give Swerve a fake hailing frequency (which Blaster even notes is too short to be real) when Swerve tells him they should open a bar together and begs him for Blurr's phone number and since then Swerve has clung to the belief that he and Blurr are best friends, when Blurr doesn't even seem to remember him at all. The last shot of Swerve standing alone quietly protesting that it ''is'' the right frequency is a pretty heartbreaking look at what's really going on behind that visor of his.

!Issue 15:
* [[spoiler: Pipes]]' death, specially after his little chat with Blaster, where he mentions that despite [[ButtMonkey everything]], he's ok and having a good time.
* [[spoiler: Once again, Chromedome and Rewind. Rewind realizing what Chromedome has done and not being sure he can ever forgive his Conjunx Endura. Rewind sacrificing himself so that Overlord can be jettisoned from the ship. Chromedome turning the Lost Light's cannons on the jettisoned cargo bay to save Rewind from Overlord. It's heart-rending.]]
** [[spoiler:Their final "goodbye" before the cell jettisoned, if you can call it that, was almost too much to bear. They can't hear each other through the glass, so we get shots from each of their perspectives as the countdown drones on in the background. There's this one panel of Rewind looking through the porthole, Chromedome's look of utter despair is reflected onto it, as Rewind says a goodbye ''Chromedome can't even hear.'']]
-->[[spoiler:'''Rewind:''' I'm sorry, Domey. I'm sorry things didn't work out.]]
!Issue 16
* [[spoiler: Issue 16 continues the numerous Tearjerkers with Chromedome and Rewind. Chromedome basically is emotionally shattered by Rewind's death and barely shows any reactions at his funeral. We than get the incredibly disturbing reveal that Chromedome has had other Conjux Endura before Rewind who he's outlived and that every time that one dies, Chromedome basically erases his memory of them to keep the pain away. Not only that, we also learned that Chromedome has no innermost energon not because he was born dry (as he had said himself), but because he had made so many deathbed offerings that he had literally none to give. Brainstorm, in previous conversations, keeps trying to get him to stop erasing the memories of his previous Conjux Enduras but isn't successful until he shows Chromedome Rewind's last movie.]]
* [[spoiler: Also, Rewind's last message to Chromedome]]
-->[[spoiler:'''Rewind''':''Your attention for a moment. This is Rewind, showing you edited footage from my database. I've probably got 0.8 seconds before game over, so hear me out. I've always been terrified that you'd die before I did, because you and me apart strikes me as intensely wrong. So promise me something. Be brave. And be strong. And keep going without me. And another thing: no more injecting. It will kill you. And remember: you deserve to be happy. The New Institute was the old you. You're a better person now—stubborn and frustrating, but wonderful. And to think, I will never see you again. One more thing—one last thing—because I don't say it enough: '''I love you.''''']]
** At the same time as this [[spoiler: Drift is exiled from the ship by Rodimus for his actions and has to leave all of his friends because of his actions. The other crew members are so shocked and angry that one of them even throws debris at Drift as he leaves. Ratchet is the only one who bothers to help Drift up after he's knocked down.]]
** Drift [[spoiler: has been a fairly unpopular character among the fandom and some the creators of the franchise from the beginning. Basically, he's been viewed as a nothing more than a stereotypical badass, fan-created Japanese samurai stereotyped character. It's sad that the only time Drift has ever elicited sympathy from ''anyone'' was when he took the fall for others, and that the last time we see him, he's still hated by just about everybody.]] Really brings his hard luck story full circle.

!Issue 17:
* In issue 17, while preparing [[spoiler:the team to take down to Luna-1's surface]] Rodimus confides to Ratchet that he knows Bumblebee and the other Autobots who stayed behind on Cybertron thought his quest was foolish, that Rodimus and his crew were just running away, and that the whole thing is some sort of joke to them.
-->'''Rodimus''': But [[spoiler: Rewind]]'s not laughing. Hyperion's not laughing. Nor Animus. Nor Shock. People have ''died'', Ratchet. People have died.
* Ratchet breaks the news to Tailgate that [[spoiler:he's suffering from cybercrosis and is going to die within the three next days.]]
** Cyclonus' initial reaction seems to be disregard about [[spoiler:Tailgate dying]] when he leaves their hab suite. Once outside, when he looks into a reflective surface, he raises his fist as if to smash it with a snarl. He stops. He just stops, with a broken and sad expression - as if thinking 'What's even the point?'. Instead, he drags his claws over his face, mutilating it.

!Issue 19:
* The confrontation between [[spoiler: Ultra Magnus/Minimus Ambus and Chief Justice Tyrest. Tyrest accuses Magnus of becoming a laughingstock due to his ByTheBookCop SuperOCD tendencies and is thus no longer worthy of carrying the title of Ultra Magnus, Duly Appointed Enforcer of the Tyrest Accord. Magnus/Ambus panics and begs Tyrest not to strip him of his title because being Ultra Magnus is his life, just before Tyrest presses a button on his staff, and the Ultra Magnus PoweredArmor falls from Ambus' body. The last shot is of Ambus kneeling dejectedly on the ground, surrounded by the remains of his armor, holding the helmet in his hands. And ''then'' he gets thrown in prison to boot!]]
** And than to top it off, [[spoiler: Tyrest kicks Magnus while he's down saying that he's failed as an Enforcer, claims that Magnus is suffering a nervous breakdown, and shows off how he's being replaced with Star Saber.]] What a {{Jerkass}}.

!Issue 20:
* [[spoiler: Star Saber murdering Dai Atlas. Made even sadder by his [[MoralEventHorizon final spiteful comments]] to Atlas.]]
-->'''Primus hates you'''.
* [[spoiler: Soundwave's pleading when the killswitch starts to affect Ravage.]]
-->Somebody ''help'' him!
* The effects of the [[spoiler:killswitch]] in general, which you would expect from an event that has [[spoiler:seemingly random Cybertronians]] suddenly dropping with smoke coming out of their eyes and mouths. [[spoiler:Soundwave panicking over Ravage, Starscream gasping Megatron's name, Red Alert quietly dying while in storage, Tarn's concern over Kaon, Fulcrum and Misfire wondering why there's no ship to pick them up, because their teammates are all effected, former friends Prowl and Chromedome dying together on opposite sides of the galaxy, completely unaware.]] And that's just the people we ''see''.
* There's also First Aid lashing out at Ratchet, because Ratchet won't let him help try to fix [[spoiler: Ambulon]], which First Aid thinks is because of the bet he made with Pharma and his own inflated sense of pride, how he thinks Ratchet believes no one will ever be as good as him, which is why he's still Chief Medical Officer. [[spoiler: And then it turns out the reason Ratchet won't let First Aid help is because Ambulon was dead before Pharma had even finished sawing him in half, and he's actually been rewiring Ambulon's corpse to turn it into a blaster (which is a whole new level of messed up right there) so they can escape.]] And even after all that, Ratchet still admits that First Aid had a point, and that if they survive, he'll step down and let First Aid take his place.

!Issue 21:
* [[spoiler: Tyrest tries to use Tailgate as a HumanShield to dissuade the away team from shooting him... at which Tailgate yells at Rodimus to ''shoot through him'' to take out Tyrest since he's dying already. Rodimus is understandably hesitant to say the least.]]
-->"I've [[spoiler: only got a day and a half left]]! Now '''SHOOT HIM'''!
* [[spoiler: Tailgate's near-death.]]
** It's even sadder when you consider that [[spoiler:per the writer, Tailgate almost died for real.]]
* The end of the story arc ends up being rather bittersweet. [[spoiler: Ambulon, Deftwing, and Dai Atlas are all dead and Tyrest and Star Saber escape. First Aid killed Pharma but he seems to be consumed with guilt over it and Rodimus had to sacrifice the Matrix map in order to stop the Killswitch, meaning the crew has no leads on finding the Knights Of Cybertron after everything they went through. And perhaps saddest of all, the hot spot the crew discovered won't reignite, meaning thousands of Cybertronians will never be born. Considering that by Prowl's calculations in the previous ongoing, Transformers are an increasingly endangered species that is edging closer and closer towards extinction, that's quite a blow.]]

!Issue 22:
* When Rewind asks some of the crew if they're happy with their lives:
** Rung admits that ''no one'' has ever asked him how he felt before -- and Rung is one of the oldest living Cybertronians we know about.
** The seemingly chipper and upbeat Drift doesn't say anything; [[StepfordSmiler he just remorsefully puts his face in his hand]].
** Swerve says:
-->"Everyone assumes that if you make jokes, you're happy. Why? Why is that?"

!Issue 27:
* Blurr doesn't remember Swerve at all, and in fact finds him annoying.

!Issue 28:
* In the six months since Dark Cybertron, Chromedome [[spoiler:has fallen apart, and now spends all day in his quarters, listening to Rewind's last message, over and over.]]

!Issue 29:
* When Trailcutter goes into medibay, it's shown that [[spoiler: Ambulon's stuff]] is still in there; apparently neither Ratchet nor First Aid had the heart to get rid of it.
* The final flashback to Megatron's trial has Rodimus sitting dejectedly in the dark because [[spoiler:he caved and took Atomizer's list of the 89 people who voted against him staying as captain, and is seemingly crushed by the names on the list.]]

!Issue 30:
* At the end of the trial, as part of the deal with Optimus to join the Lost Light, Megatron has to publicly denounce the Decepticon cause, declaring it a failed ideal and ordering any who still wore the badge to stand down. After he is done, he silently buries his face in his hands.
* Ratchet points out to Rodimus that [[spoiler:the voting records are fake because his name is not on the list.]] Rodimus' expression says it all.
* In the end the Lost Light basically disintegrates, forcing the crew to abandon it. Given how they had largely come to view it as their home, that's a pretty big blow.

!Issue 31:
* In the flashback, [[spoiler:Pipes]] being [[HarsherInHindsight as excited and optimistic as can be]] for the trip.
* Riptide's anxiety whilst remembering the eight step program is instantly relatable for any academic strugglers.
* Tailgate admitting that he's scared out of his mind to Cyclonus.
* The whole concept of the [=MTO=]s, and their gradual degeneration into mass produced cannon fodder, is plenty messed up and sad. Skids in particular is angered with the process.
* As more and more crewmembers disappear, Nautica breaks down and starts freaking out about how she may never see her friends from Caminus again.

!Issue 32
* Megatron and Ravage's heart-to-heart talk, when Megatron admits he sees himself as a monster. And the panel where Ravage has the most heartbroken look imaginable during all this.
** During this conversation Megatron finally admits that he is ''old''. And that his best days are long behind him, even without the PowerLimiter fuel the Autobots are keeping him on. He finally admits to being what he really is: a tired old man full of regrets.
-->'''Megatron''': Look at me Ravage. I'm '''old'''. Old and weak. Their poison makes me '''brittle''', but even at full strength I'm long past my prime. My spark '''flickers''' when once it '''flared''', and this body...oh, this nonsense body. It doesn't graft to the spark like the others. There's no purchase. No '''bite'''.

!Issue 33
* What [[spoiler:Rewind]] had to endure at the hands of the DJD. [[spoiler:They have him film the massacre of the rest of the crew to ensure Chromedome's survival, but once this is finished, they move the goalposts and insist that Chromedome has to erase his own memories of Rewind as well. When he refuses despite Rewind's pleas, Vos kills him right in front of his Conjunx Endura.]]
* Nautica [[spoiler:finding Brainstorm's corpse buried in the wreckage of his lab]] is pretty hard to read, especially considering just how close they had gotten over the past few months. Gets infinitely worse when [[spoiler:he's revealed as the Decepticons' mole, and she is in desperate denial.]]
* This, when [[spoiler:Rewind believes that he's going to have to die to bring the other ''Lost Light'' back.]]
-->'''Rewind:''' On your Lost Light, [[spoiler:me and Domey]]... are we still strong?
-->'''Megatron:''' [[LetThemDieHappy ...You're inseparable.]]
* [[spoiler:[[SugarWiki/HeartwarmingMoments Chromedome and Rewind's silent reunion]].]] Just as Skids said, no words - no questions. No words are needed.

!Issue 34
* ''Everything'' concerning Megatron and Terminus.
* Trailcutter reminds us that, occasional drunken hijinks aside, he's a good guy who would risk his own life to save someone Bluestreak, Mainframe, and First Aid have already given up on. [[spoiler:The someone in question turns out to be a DJD member, and poor Trailcutter ends up eviscerated for his trouble -- just when things were finally looking up for him.]]
* What nearly happened to Megatron; [[spoiler:he almost had his personality altered, which would have included dulling his intelligence, so that he wouldn't write against the senate or Functionists anymore. He actually starts crying (Energon) at one point.]]

! Issue 35
* The fate of [[spoiler:Alternate!Timeline]] Dominus Ambus. [[spoiler:The Functionist Council try to silence him by performing a new form of [[AnArmAndALeg Empurata]] on him and replacing his head with a TV screen [[AndIMustScream forcing him to only be able to communicate with on screen text.]]]] And then [[spoiler:when the Council finds out that he hasn't given up, they remotely hack his mind and delete most of his personal vocabulary. [[MindRape This means that not only is he reduced to only responding in the most basic of words (Yes, No, Up, Down, Go, Stop etc.) but he is incapable of understanding anything but those words.]]]]
--> '''Rewind''': [[spoiler: ...and the words he's lost—when you speak to him, the words he's lost—he doesn't know what they '''mean''' anymore! And there are certain words, Minimus—'''tiny''' words—'''important''' words—there are certain words you can't afford to lose.]]
** [[spoiler: Look at what Dominus is doing in that second-to-last panel. He doesn't know the words any more, but he's still cradling Rewind as he dies.]]

!Issue 36
* [[spoiler:The conversation between Past!Orion Pax and Future!Megatron.]]
* [[spoiler: Rodimus tries to give Trailbreaker information that will prevent his later death, only for Trailbreaker to grab Chromedome's hand and accidentally wipe his own memory, thus negating the info. Not only that, but it's implied that this may have partially caused Trailbreaker's alcoholism.]]
** Also note that [[spoiler: it's suggested Rodimus would've failed to save him regardless. Issue 35 shows that the DJD blew up the shuttle Trailcutter, First Aid, Bluestreak, and Mainframe used before they got off Ofsted XVII. So even if Trailbreaker ''had'' been able to follow Rodimus' advice he would've been blown to bits anyways.]]
* [[spoiler: The crew also indirectly causes Orion and the Outliers to lose their memories of Roller disappearing, thus dooming him to whatever happened. Even worse, there's an increasingly strong implication that Roller is in fact the younger version of Tarn and him being accidentally left for dead is his StartOfDarkness.]]

!Issue 37
* The flashback of Whirl's tools and shop being destroyed, including his shocked (pre-empurata) face. He also finds out it was [[spoiler:the Functionists controlling the Senate who had him undergo empurata, and kills one of the guys who tells him this.]]

!Issue 38
* The scene in the 'Con Facility opens up with Brainstorm monologuing as he levels a gun at [[spoiler:the newborn Megatron.]] Only later do we find out that [[spoiler:Brainstorm has never killed, he'd been standing there for 10 minutes trying to work up the nerve.]]
* Brainstorm's ultimate motivations. [[spoiler:Before the war he fell in love with a fellow scientist named Quark, only to for Quark not to reciprocate to the same level ([[UnrequitedLove if he even realized how Brainstorm felt]]). During the war, Quark was arrested and died in a HellholePrison. Brainstorm, driven near-mad with grief, decided to use quantum engines to create the time machine briefcase and go back in time to prevent Quark's death. After Chromedome lost Rewind, he decided to spare "everyone" from the war by changing Megatron's life experiences and, when that failed, killing him.]] The worst part? [[spoiler:Had he succeeded, Quark would have become a top scientific officer in the Functionist regime. Judging by how Brainstorm stops Rewind from looking him up in his database, he's at least partially aware of where Quark might have ended up.]]
* The look on Brainstorm's face as [[spoiler:he watches Quark from afar.]] The mouthplate obscures his rueful happiness not at all.
* Rewind begins shaking and losing his composure after [[spoiler:murdering "Megatron,"]] and remarks to Chromedome that he should be appalled at him. Chromedome refuses, leading to a [[SugarWiki/HeartwarmingMoments heartwarming moment]].
* At the issue's end, everyone is celebrating in Swerve's bar and enjoying themselves... except Megatron, who is sitting glumly in his room, reevaluating his life while Ravage tries to comfort him, and [[spoiler:Brainstorm himself, locked in the brig with a look of despair on his face.]]

!Issue 39
* As it turns out [[spoiler: Tarn is actually disturbed by the violence the DJD commits and wears his mask to hide the fact that he closes his eyes out of disgust whenever they indulge in torture. His narration also has him constantly berating and criticizing himself, suggesting that he's filled with self loathing. It's almost sad enough to you briefly forget he's a murderer.]]

!Issue 40:
* The reveal that Ten is sentient, not just a mindless drone, is a punch to the heart considering the way he's treated by Swerve and others.
* The revelation that by killing Megatron in the past, Brainstorm fully intended to negate his own existence; he was a Made To Order soldier, created during the war. No war, and he would never be born. He wasn't trying to save Quark in the hope that they would wind up together somehow, he fully knew that it was impossible, and was instead trading his life for Quark's.

!Issue 42
* At the party at the end of the issue, Cyclonus is sitting glumly at the sidelines like usual, but than "Power of Love" comes on over the radio and he decides to go ahead and dance with Tailgate... and than walks over to find that [[ToxicFriendInfluence Getaway]] got there first.

!Issue 43
* The reveal that Swerve has been holed up in his hab suite since the start of the season 2 comics and that the Swerve we've been seeing is just a holomatter avatar he's been projecting while he slowly dies from an old war wound with nobody else the wiser.

!Issue 44
* The last page. The Lost Light crew have found the planet of the Necrobot, an ancient Transformer who travels the galaxy cataloging the deaths of every Cybertronian in existence. Each one has a holographic statue in their image, that gets taken down when they die. At the feet of the statues are beautiful blue flowers; each flower contains the residual spark energy of every Transformer they have killed, directly or indirectly, and it takes at least a dozen deaths to light each one. Since the Cybertronian race is dwindling, the Necrobot has concluded that there is not a single statue left without at least one flower. ''Every'' character in the franchise is a killer at this point. In the final page, Megatron ([[{{Irony}} who only agreed to come to this world to forestall his judgement a little longer]]) finds his own statue. The flowers stretch into the horizon, with no end in sight.

!Issue 45
* The Scavengers have not been handling Megatron's side-change and Starscream's election well. They've abandoned their plans to go home out of despair and distrust and have basically just been bumming around the outer rim since. Krok is doing the worst; his anxiety is getting worse and he's becoming increasingly temperamental, snapping at the rest of the group for not doing anything with their lives.
* We see more of Grimlock's deficient mental state. He's become so disabled that sometimes he just wets himself and he can't even read or write. Misfire is trying to help, but is having his nerves visibly frayed.
