* ''Webcomic/{{MAG ISA}}'' -- The demon gets an [[http://mag-isa.thecomicseries.com/comics/pl/119601 OH CRAP moment]] after realizing that he'll soon get his ass kicked after being driven out from the boy.
* In ''Webcomic/GoneWithTheBlastwave'', the [[StraightMan Sniper Guy]] and the [[BunnyEarsLawyer Flamethrower Guy]] have finally made it back to a camp of the [[ColourCodedForYourConvenience Red Army]] and are taken to the commander for debriefing, together with the squad that found them.
--> '''Sniper:''' So why didn't you become a group leader?\\
'''West:''' Don't know. They basically just asked my kill count.\\
'''Sniper:''' Your kill count? ''[{{beat}}]'' [[http://www.blastwave-comic.com/index.php?p=comic&nro=33 Oh. My. God!]]
* ''Webcomic/{{Lackadaisy}}''
** Rocky and Ivy think they've beaten the Pig Farmers, [[http://www.lackadaisycats.com/comic.php?comicid=110 until...]]
-->'''Rocky''': "HA! HAHAAAA...oh."
** And when [[spoiler: Rocky gets smacked in the forehead with a hearse]] [[http://www.lackadaisycats.com/comic.php?comicid=111 a page later.]]
** Not to mention the last two panels [[http://www.lackadaisycats.com/comic.php?comicid=17 here.]]

* In ''[[http://www.planet-bob.org/heritage/?strip_id=0 Heritage]]'', the mysterious [[ArrogantKungFuGuy Jack]] is understandably surprised when the otherwise ordinary hero Frate suddenly gains super angel powers in the middle of a fight.

*** [[ThatsGottaHurt Ooh, that's gotta be]] uncomfortable...
** [[http://www.giantitp.com/comics/oots0105.html "That... is considerably more resistance than I was expecting." "Ayup."]]
** When Roy and Xykon battle for the first time, Xykon gives Roy an Oh Crap [[http://www.giantitp.com/comics/oots0112.html moment]] that triggers a brief HeroicBSOD. When the HeroicBSOD ends, it's [[http://www.giantitp.com/comics/oots0114.html Xykon's turn]].
** For a '''heroes''' example, check this [[http://www.giantitp.com/comics/oots0267.html bottom-right panel]].
** Roy has a literal one in [[http://www.giantitp.com/comics/oots0332.html strip #332]], when he realizes that he screwed up his question to the Oracle.

** Another [[http://www.giantitp.com/comics/oots0408.html quite literal instance]] from Belkar, as he stands defenseless before Miko.
** Even within the limits of being a skeleton drawn with stick-figure art, Xykon's [[WideEyesAndShrunkenIrises expression]] when he's confronted by [[spoiler:the ghost-martyrs of the Sapphire Guard, led by Lord Soon himself]] in [[http://www.giantitp.com/comics/oots0449.html this strip]] conveys this reaction loud and clear. Later in the same battle, [[http://www.giantitp.com/comics/oots0462.html it happens again]], after [[spoiler:Soon reveals that he knows exactly how to ''permanently'' kill a lich. And then ''Soon'' has one when he realizes Miko's about to destroy the crystal]].
** [[http://www.giantitp.com/comics/oots0512.html "OK, so I've got bad news, and I've got bad news."]]
** Belkar Bitterleaf, though a hero ([[HeroicComedicSociopath arguably]]), suffers one in [[http://www.giantitp.com/comics/oots0568.html #568]]. [[spoiler:After finally getting fed up with an annoying oracle, Belkar kills him. Unfortunately, he also has a Mark of Justice on his head, set to go off when he kills a person within the sphere of influence of a town. And guess what popped up around the oracle's home last week?

--->'''Therkla:''' Did that tree...\\
'''Qarr:''' ...just say "Oww"?
** Vaarsuvius is [[DroolHello like this]] [[http://www.giantitp.com/comics/oots0626.html here]], which begins a series of escalating Oh Crap moments on [[http://www.giantitp.com/comics/oots0627.html the]] [[http://www.giantitp.com/comics/oots0628.html following]] [[http://www.giantitp.com/comics/oots0629.html pages]], until...

** Xykon again when [[spoiler:his phylactery is about to fall into the Snarl's prison.]] He has a brief moment of relief when it doesn't, only to get the look ''again'' when [[spoiler: it instead falls into a sewer with pipes leading to a sewage plant, a labyrinth, and the ocean]].
** Admit it. You were thinking it about halfway through [[http://www.giantitp.com/comics/oots0694.html this page.]]
** [[http://www.giantitp.com/comics/oots0759.html Elan finally realizes his Dad is evil.]]
*** Also, when [[http://www.giantitp.com/comics/oots0763.html Elan realizes that even if the Order manages to take his father and his allies down, they/he would be remembered for all time.]]

** V's expression in the penultimate panel of [[http://www.giantitp.com/comics/oots0842.html this comic]] speaks volumes.
** Durkon gets this look [[http://www.giantitp.com/comics/oots0876.html here]] when [[spoiler: Malack reveals that he snuck a code word into Mass Death Ward that lets him dismiss it.]]
** Malack gets one once Zz'dtri [[spoiler:removes his Protection from Daylight spell.]]
** "Hello, Nale. Walk with me. We have a lot to talk about."
* ''Webcomic/GirlGenius'': These Wulfenbach soldiers, when it [[http://www.girlgeniusonline.com/comic.php?date=20070702 turns out]] the locals fully support Agatha.
** Also the Wulfenbach soldiers in [[http://www.girlgeniusonline.com/ggmain/doublespreads/ggcoll06_122_123.html this strip]].
** And Agatha's dingbots in [[http://www.girlgeniusonline.com/comic.php?date=20060609 this one]].

** in [[http://www.girlgeniusonline.com/!.images.page/navbuttons/nextday.jpg This Comic]] when General Gkika sees Wolfenback enter Mechanicburg holding a cross between a portable big red button and a pokeball.
* You could make a drinking game for all these moments in ''Webcomic/SchlockMercenary''.
** Ably demonstrated in the fourth panel of [[http://www.schlockmercenary.com/2002-01-11 this]] strip.
** Not even being [[http://www.schlockmercenary.com/2002-05-14 harm incarnate]] is defense against [[http://www.schlockmercenary.com/2002-07-28 an Oh Crap moment]].
** "[[http://www.schlockmercenary.com/2002-09-06 Heh. It looks like all you did was take a hullcutter to the barrels.]]" (The barrels being in large part, the heavily computerized weapon's circuitboard.)
** And used with the appropriate sentence [[http://www.schlockmercenary.com/2003-05-04 here]].
** [[http://www.schlockmercenary.com/2003-11-13 One from Tagon]].
** Although the tension is deflated a moment later, Kevyn suffers this in Book 6, Part IV, after [[http://www.schlockmercenary.com/2005-03-25 Ennesby gives a damage report.]]
-->'''Ennesby''': Low-yield kinetic strike to the fore dorsal turret ... Hull-breach above the wardroom!\\
'''Kevyn''': Wait, dorsal turret access is right up ''there.'' We're ''in'' the wardroom.
** One from "[[http://www.schlockmercenary.com/2006-05-02 San Asimov's Finest]]"
** And in [[http://www.schlockmercenary.com/2007-08-18 this one.]] [[note]]For those unfamiliar with the comic, Schlock there is talking to some rogue nanites that have infiltrated his eyes and hijacked them in order to create a simulated space to speak with him. Combat between members of his species half consists of using their extremely potent and adaptable immune systems to counteract the various chemical cocktails their opponents synthesize in an attempt to melt and absorb them. And he's just revealed that the plasma cannon he's been "impotently" waving at the nanites was actually just a familiar visual metaphor for his immune system. They have ''very'' good reason to look so worried in that third panel.[[/note]]
** [[http://www.schlockmercenary.com/2009-11-01 Rule 3]]: An ordnance technician at a dead run outranks ''everybody''.
** A twofer in the last row of [[http://www.schlockmercenary.com/2011-10-16 this]] comic. Even if it's just a still picture, the last target's eye view of an oncoming missile is never happy.
** Schlock is fairly easy to fix after any mechanical trauma and became less than cautious about having such problems. He also is a walking arsenal. [[http://www.schlockmercenary.com/2012-04-14 The team didn't fully connect the two facts before...]]
** [[http://www.schlockmercenary.com/2012-06-26 A particularly nightmarish]] revelation left the Doctor, Tagon, Shlock, and Ennesby all similarly horrified.
* [[http://www.drowtales.com/longestwait.php?order=date&id=18 Diva'ratrika's face]] in the last panel of this strip of ''{{Drowtales}}''. And then [[http://www.drowtales.com/longestwait.php?order=date&id=22 a couple pages later]] when she realizes just how deep the treachery extends into her own family.
** Rikashar also has a FreakOut after [[spoiler:Ariel beats the crap out of him when he tries to abduct her and make her his wife]] with his reaction following [[http://www.drowtales.com/mainarchive.php?order=chapters&id=1115&overview=1&chibi=1&cover=1&extra=1=1&check=1 here]], and the last panel of the same page is more of an "Aw, shit" after he sees who's caught up with him.
*** Yet another from the same comic happens in the seventh panel of [[http://www.drowtales.com/mainarchive.php?check=1&order=chapters&overview=1&chibi=1&cover=1&page=1&extra=1&id=1140 this]] chibi-page, which parodies events from that same chapter.
* ''Webcomic/LastRes0rt'''s Slick invokes it upon finding out that apparently his team is so far behind the others, Cypress has [[TonightSomeoneDies already written them off]].
* ''Webcomic/{{Goblins}}'': CLOSE THE WEST GATE!
** Later, [[spoiler:Thaco]] gets one when [[spoiler:Goblinslayer illuminates the darkened sewer, negating Thaco's single advantage, (his ability to see in the dark) resulting in a straight up fight between the two adversaries that Thaco cannot possibly win.]]
*** In the same fight, [[spoiler:Goblinslayer]] also gets this, when [[spoiler:Thaco remembers he is a Monk and can snatch arrows, making Goblinslayer's ranged attacks useless.]]
** Saves a Fox's entire self-image was that people [[ScrewDestiny are not bound by their destiny]]. When the fated day came when a fox got stuck in her home village's food supply, she snapped its neck in order to spite her fate, and saved the tail as a memento. That's not the ProphecyTwist resulting in her OhCrap moment... [[spoiler: Dies Horribly informs her that the symptoms she described the fox having was that of Sunset fever, something that causes animals to become delirious before dying a horrible, painful, and silent death. Saves A Fox gave it a MercyKill before it could suffer the worst effects of it. The look on her face that not only is her entire self-image a lie, but her friend whose name reflecting his destiny is "Dies Horribly" is not able to escape his fate either tells us she's heading right into HeroicBSOD territory.]]
** The Psionic Minmax alt was supremely confident until he realized [[spoiler:Kin announcing his intent to kill everyone in the Maze of Many had united ''all of the survivors'' against him]].
*** [[FromBadToWorse It got worse]] [[http://www.goblinscomic.org/07112013/ for him.]]
* In the webcomic ''{{Narbonic}}'', Dave's normal state of being becomes one big Oh Crap moment.
* ''Webcomic/DanAndMabsFurryAdventures'' has its share of Oh Crap moments, particularly in the latest arc. One of the better ones has to be Regina's, starting on page [[http://www.missmab.com/Comics/Vol_973.php 973]]. Of course, this being DMFA, it's the page's ''punchline''.
-->'''Regina:''' ''(thinking)'' Should be easy. I nearly pulped him last time we fought. I mean, it's been what, six years? What could he have learned in that time?\\
''* K-shnk! K-shnk!* ''\\
'''Dan:''' I learned to hear thoughts. Among other things.\\
'''Regina:''' ''(thinking)'' OK. New plan. Piddle self. Run.
** And like many such moments, it doubles as a CrowningMomentOfFunny
* ''Webcomic/TheAdventuresOfDrMcNinja'':
** [[http://drmcninja.com/page.php?pageNum=38&issue=15 King Radical]], when he hears about Dr. [=McNinja=]'s new motorcycle.
** It's ''very'' subtle, but the last panel of [[http://drmcninja.com/page.php?pageNum=33&issue=15 this page]] is an excellent example.
** [[http://drmcninja.com/archives/comic/23p09/ Gordito]] gets a big one in the second-to-last panel when he realizes his BadassMustache is useless against the principal... and he's going to have to shave it.
* In ''Webcomic/{{Earthsong}}'', Willow has one when she's walking through the woods at night ... something tugs on her cloak ... and she looks up, right into the teeth of a hungry vampire.
* ''Webcomic/HannaIsNotABoysName'' has its share of these moments, as Conrad [[http://hanna.aftertorque.com/?p=194 demonstrates]].
* In ''Webcomic/{{Starslip}}'', Vanderbeam, understandably, has this on his face for four panels in a row after the Anthelerix [[spoiler:relocate ''every known celestial body and planet'' to another part of the Milky Way.]]
* [[Webcomic/DominicDeegan Jacob Deegan]] gets [[http://www.dominic-deegan.com/view.php?date=2009-08-28 this]] little moment. Also an occurance of PrecisionFStrike.
** Also, Dominic himself, when [[http://dominic-deegan.com/view.php?date=2011-02-11 facing down the Beast.]]
* ''Webcomic/CaptainSNES'' has a nice one from [[{{Lufia}} Gades]] when the protagonist, Alex, launches his side of a very, very short BeamOWar match, which didn't last very long (and neither did Gades). [[DoesThisRemindYouOfAnything Alex's beam was much bigger]].
* If Ed had had a face in [[http://megatokyo.com/strip/378 this strip]] of ''Webcomic/MegaTokyo'', it would have had this expression.
* ''Webcomic/{{Erfworld}}'': Charlie has the distinction of getting one [[HeWhoMustNotBeSeen offscreen]] during this exchange with Parson over the Eyebooks, after just getting Parson to use one of the calculations he owed Charlie to assess whether it was worth giving up the rest of the calculations in exchange for information from Parson.
-->'''Charlie:''' That was clever though, right?\\
'''Parson:''' Sure. Determining the decision not to spend all the calculations. Cost: one calculation.\\
'''Charlie:''' [[SmugSnake :)]]\\
'''Parson:''' Teaching me that my bracer can make sophisticated predictions about the future? Priceless.\\
'''Charlie:''' [[VisibleSilence ...]] [[OhCrap :(]]
** Later on, pretty much all of Gobwin Knob (especially Stanley and Wanda, [[TheStoic who had been unshakable beforehand]]) get this when [[spoiler: Faq's Turnamancer linked with Charlie manage to force them to end their turn]].
* In ''[[Webcomic/EightBitTheater 8-Bit Theater]]''... well they happen a ''lot''. But the best may come [[http://www.nuklearpower.com/2009/10/01/episode-1179-everything-will-be-fine/ here]], when the ultimate {{Jerkass}} discovers he's finally bitten off [[PhlebotinumOverload more than he can chew]].
** This classic, when Black Mage sees Muffin:
--->'''Black Mage:''' Teeth... like daggers... eyes... also like daggers...
--->'''Fighter:''' How does that work?
--->'''Thief:''' [[IncrediblyLamePun Piercing gaze?]]
--->'''Fighter:''' You're on fire today!
--->'''Black Mage:''' Scales noticeably dagger-like...
** Each character gets at least one, but Black Mage, as the resident ChewToy gets the most of them. It doesn't help him that his face is EASILY the best suited for these expressions.
** The universe itself goes OhCrap when [[spoiler: Black Mage becomes the ruler of Hell.]]
* [[http://www.egscomics.com/?date=2007-03-20 A minor one]] in ''Webcomic/ElGoonishShive'': Nanase uses her fairy doll to contact Ellen, and tries to wake her up by tickling her nose with her tail. Her reaction when she realises she's about to get messily sneezed on is hilarious.
** There's a slightly more major one [[http://www.egscomics.com/?date=2010-01-06 here]]. More of an awkward "oh crap" than a dangerous one, but just as expressive...
** [[http://www.egscomics.com/?date=2010-03-31 Another awkward example]] is Elliot's reaction to Noah bringing up his parents' death.
** Justin [[http://egscomics.com/?date=2011-01-14 here,]] when George reveals that he knows that Elliot is Cheerleadra, if he's wrong on a few minor details.
** And the two-panel [[http://www.egscomics.com/?date=2011-06-15 realization]] which used this trope to the letter.
* In ''Webcomic/SlightlyDamned'', the latest villain to cross the heroes' path gets a short one when Kieri slices his bow in half.
** An earlier one being when [[DeadpanSnarker Rhea]] stole [[http://www.sdamned.com/2005/07/07152005/ Buwaro's Star Pendant]], and then found out that it kept his SuperpoweredEvilSide repressed.
* In ''Webcomic/VGCats'', Aeris finds out the hard way that Coach [[http://www.vgcats.com/comics/?strip_id=289 is controlled by a completely different type of bot...]]
* ''Webcomic/CtrlAltDel''. The look on 1's face [[http://www.cad-comic.com/cad/20100308 here]] just says it all.
* The girls in ''Webcomic/QuestionableContent'' have this moment when [[spoiler:the Vesp Avenger's scooter turns into an attack robot]].
-->'''Faye:''' All right! We're well and truly fucked.
-->'''Martin:''' And not the fun, slightly sticky kind of fucked!
-->'''Faye:''' [[IncrediblyLamePun That was TERRIBLE.]]
-->'''Martin:''' YOU try being funny when your life is flashing before your eyes!
** More recently, in strip [[http://questionablecontent.net/view.php?comic=1689 1689]], Faye's expression in the last panel. [[spoiler: She realized that Marigold knew about her and Angus being interested in each other.]]
** Mieville the cat's [[http://www.questionablecontent.net/view.php?comic=1585 reaction]] to Hannalore's [[TechnicallyASmile attempt at a smile]]. Odds are that most people would react the same way the cat did.
* In ''Webcomic/FakeNewsRumble'', Jon gets one in his fight with [[spoiler: a possesed Colbert.]] Seen [[http://www.star-crossedcomic.com/fnr/fnr_7_7.html here]].
* From ''Webcomic/CaseyAndAndy'': [[http://galactanet.com/comic/view.php?strip=50 "This has 'bad day' written all over it."]]
* ''Webcomic/SluggyFreelance'' (sorted by chapter or story or theme as appropriate):
** In "Vampires":
--> '''Valerie''': "I told you to stay out of my business, you ''bitch''! Once you're an immortal I will take great lengths to see you suffer in ways impossible for a mortal to understand. Don't think Sam can protect you, he is far too ''weak''!
--> '''Zoë''' (thinking): ''Wow! Vampire PMS!''
--> '''Valerie''': "We can read thoughts, you know."
--> '''Zoë''' (thinking): ''Oh crap!''
--> '''Valerie''': "''That'' is an understatement."
** "Mecha Easter Bunny" is practically built on a long sequence of these.
*** Bun-bun when he torches the Mecha Easter Bunny and finds that he's only revealed an unharmed, heavily armed robot.
*** When Bun-bun pulls a bazooka on the Mecha Easter Bunny and right at its face, it tries to frantically scramble backwards, and its "internal robot view feed" also shows the text ">OH CRAP!!!!"
*** Mind you, a bazooka shot to the face barely scratches the MEB, leaving Bun-bun to have another "oh crap" moment.
*** Santa Claus when he realises the MEB, which he built, is about to kill innocent people. "Ho-ho-holy $#!%!"
*** Santa again when Bun-bun manages to destroy the MEB, and Santa knows he'll be coming after him next. "Ho-oh crap."
*** Finally, Bun-bun when he thinks he's decapitated Santa and it turns out it's a dummy full of explosives just about to go off.
** In "Dangerous Days Ahead": When Hereti-Corp troops led by Mr. Killum disable Riff's robot with an EMP, only to find that inside is actually Oasis, a OneWomanArmy brainwashed to kill all Hereti-Corp personnel on sight. (Killum: "Oh shi*...")
** In "Holiday Wars":
*** A scene where [[ItMakesSenseInContext a Thanksgiving turkey medic finds out that what appeared to be another turkey is in fact a monster that steals other people's face and hands (in this case wings), being ridden by Bun-bun.]] She's so shocked she lays an egg while still staring at them.
*** The AnthropomorphicPersonification of the year 2003, when facing [[KillerRabbit Bun-bun]] with the combined powers of the embodiments of nearly all holidays.
--> '''Father Time:''' [[foldercontrol]]

[[folder: [[Evil Overlord Overlord ]]
Bun-bun has arrived on the wings of the Groundhog's Shadow, and now faces the one who stole the Deus Egg. The Year ''2003'' himself!]]
--> '''2003:''' "I have done everything I can to thwart you peacefully, Bun-bun, but I've trained half my life for this fight. You came for the egg, I'll leave with your head!"
--> '''Bun-bun's multi-part switchblade scythe [[DoomyDoomsOfDoom of doom]]:''' ''KA-CLIKITY CLICK KLAK''
--> '''Father Time:''' [[/folder]]

[[folder: 2003 is even now soiling himself... ]]

--> '''2003:''' ''"Would you quit narrating this?"''
** "That Which Redeems":
*** [[http://www.sluggy.com/comics/archives/daily/040823 oooo-This is gonna hurt]].
*** At a meeting of the demons where Psyk tries to talk about the Canada situation but Lord Horribus isn't paying attention, Psyk snaps to him about how he's obsessed with finding Torg. The strip ends with Psyk and all the other demons present staring with the realsiation of his having gone too far. (The next one starts with the same picture: "Still going 'oops!'")
*** "Mospinispinosp" is a demon consisting of a snakey humanoid female body (Mosp) with two small talkative snakes (Isp and Osp) for "hair". At one point, Isp and Osp wait for Mosp to apparently be asleep and confide to another demon that she's been helping mortals and betraying the demons. They certainly have an "oh crap" moment when they realise the "demon" was just a sock puppet on Mosp's tail, and when they see the diagram of what she's going to do to them now (which is to make "earrings" to clip their mouths shut).
*** Later Isp and Osp again when they think Mosp has killed their [[DemonLordsAndArchdevils Demon Lord]] -- and even more so when they find out she failed. "Holy demon-crap!"
** "A Time for Healing": Jane, an intelligent zombie who's giving Gwynn a TheReasonYouSuckSpeech while preparing to eat her brain and mocking her claims of a TomeOfEldritchLore that gives her magical powers -- when she pushes her BerserkButton and finds out that that's what activates said powers, and they're way out of her league. Her face is not shown at the Oh Crap moment; it's instead indicated effectively by her surgical saw winding down.
** "4U City Red - Another Year in the Life of a Villain": An ordinary, non-[[TalkingAnimal talking]] frog (usual line: "'''CROAK.'''") is caught in a building after a somewhat literal-minded OneWomanArmy has been ordered to kill everyone in it.
--> "'''[=CRapK=].'''"
** A RunningGag where Dr. Schlock thinks he's just got out of trouble and then Riff appears and sticks a laser cannon to his head.
* Returns various times in ''Webcomic/MenageA3'':
** [[http://www.menagea3.net/d/20080823.html Gary realizes]] how Matt and Dillon have tested his new drawing table's strength.
** Gary realises that his [[http://www.menagea3.net/d/20090924.html mouth ran away with him]].
** Sandra is the victim of a BilingualBackfire [[http://www.menagea3.net/d/20110120.html here]].
** Zii has a great one in [[http://www.menagea3.net/d/20110106.html this strip]].
* When Paulus, a wealthy Roman citizen, decides that he's tired of being a bachelor, he has one of his servants put up a personal ad in the Forum. [[http://comics.shipsinker.com/?id=139 It gets rather more of a response than he expected.]]
* ''Webcomic/{{Digger}}'': [[http://www.diggercomic.com/?p=504 "Meep."]]
* In ''Webcomic/ExterminatusNow'', a random paranoid tries to temporarily ingratiate himself in the protagonists so he can hide from "government spooks". The main characters proceed to inform him that those people are likely just foreign businessmen, while revealing enough information to make the guy realize ''they'' are government spooks.
** And [[http://exterminatusnow.co.uk/2011-07-31/comic/the-cesspool/ultimatum/ here's]] the reaction of the original team members when Rogue horribly insults Lothar.
* In ''Webcomic/TwoEvilScientists'', [[spoiler:a robotic clone of]] Dr. Wily uses [[spoiler:[[ToxicPhlebotinum Evil Energy]] to revive Bass at the insistence of his daughter Cream.]] It works, and he has a few moments to enjoy his success until he realizes [[spoiler:he brought ''[[TheSociopath Bass]]'' back to life, and he CameBackWrong.]]
* In ''Webcomic/{{Homestuck}}'', [[spoiler:Eridan]]'s [[http://mspaintadventures.com/?s=6&p=005433 reaction]] to [[spoiler:his victim Kanaya coming back as a glowing super powerful Rainbow Drinker (the Troll version of a ''vampire'') that just ''snapped his wand'' leaving him unarmed while she ''revs up her chainsaw'']] is [[CrowningMomentOfAwesome priceless]].
** Even better and even more cathartic? [[spoiler:Bec Noir's reaction to seeing PM arrive in the troll's session, wearing the White Queen's ring and looking ''pissed. Off.'']]
** Two from two different characters, one after another. The first is when Rose realizes that it's not a memory when the Draconian Dignitary is in Dave's room with her. The next is when Dave remembers that he's not in his room. [[http://www.mspaintadventures.com/scratch.php?s=6&p=005839 He's still asleep on Derse.]]
** Aradia's reaction to seeing Sollux is as cheerful as you'd expect from two friends (or more) meeting up for the first time in real life... right until she realises he's BrainwashedAndCrazy.
** A three-way version occurs when Jake and Jane stumble into [[spoiler:Derse right before it starts falling apart]] and Dirk comes across them. All three of them proceed to freak out.
