* When, at the climax of Capt. James' character arc, he overcomes his paralyzing self-doubt to be with his beloved Gwaednerth Smith.
** The story of their ensuing domestic bliss is chronicled in the spin-off, ''[[Series/{{Torchwood}} Peacemist: Nicer Post]]''.
*** In a related piece, the wonderful story of how they single handedly disposed of death, meaning that people could live happy immortal lives, as chronicled in [[Series/TorchwoodMiracleDay Peacemist: Destruction of Death]].
*** Though he still laments in every episode that even with all the alien tech at their disposal, [[RunningGag their coffee still tastes like sweaty socks run-off filtered through wet dog hair.]]
** Don't forget the exchange between James and the (Tenth) Inspector in "Intersection of the Parallels", which serves as a CallBack to [[spoiler:Lily's ascendance (see below)]]:
--> '''Inspector''': Why did you save me?
--> '''James''': [[spoiler: The Good Lamb always returns to its shepherd, remember?]]
* Aiden's [[ShutUpKiss response]] to finally finding out that Angie had a crush on him their entire childhood was heartmeltingly sweet.
* When Veneziana and [[{{Spoonerism}} Ked Nelly]] jetboat off [[RidingIntoTheSunset into the sunset]] together at the end of the episode "Moon of Water"—it was truly LoveAtFirstSight.
* In ''The Horrendous Space Kablooie'': After having had his beloved bowler hat destroyed in ''The Promethium Closes'', Brooke Rhapsody uses a matter-alteration setting on her gun to create a new one in midair. The look of thanks on the Inspector's face when Angie catches it and plops it on his head is ''heartmelting.''
* After [[{{BadassNormal}} Constable Reginald Wigglesworth]] compromises his ethics and humanity to gang press a team of [[{{Monsteroftheweek}} Timelocked Snarling Lions, a dying Rostraans seeking glory and former Associate]] and Reginald ex turned soulless Time Deviant [[{{HeelFaceTurn}} Camilla Sea ]] into rescuing the [[{{PsychologicalTormentZone}} Inspector from the Paradox Torment]]. The following conversation was to this troper borderline {{Tearjerker}}..
--> '''Inspector Spacetime:''' Why did you do it Reginald? You sacrificed your name, what you stood for. Even what's left of your poor broken heart to save me.
--> '''Constable Reginald:''' Somebody had to do it, Inspector. You're the boss and I am the loyal sidekick. And the cost was... acceptable.
--> '''Inspector Spacetime:''' (''somberly'') Surely, I am not that good of a boss.
--> '''Constable Reginald:''' No. (''beat'') But you're that good of a friend. Besides you would have done the same for me.
--> '''Inspector Spacetime:''' -Without a second thought or a moment's hesitation, old friend, and the Universe herself could not stop me.

* Along with being quite a TearJerker, Lily's ultimate choice to leave this physical universe and embrace her destiny as the Good Lamb by joining the Pantheon of Immortals counts as a HeartwarmingMoment just for the sheer selflessness of the act. Her goodbye to the Inspector is adorable, too.
--> '''Lily Taylor:''' You are my shepherd, Inspector, and I am yours. Watch over our flock for me.
--> (Lily shines with the energy of the Good Lamb, and ascends into the heavens. The Inspector smiles, proud and yet regretful at his associate leaving. We linger on one final shot of Lily, clad in the Good Lamb's white robes and carrying a shepherd's crook, as she enters the Pantheon of the Immortals. Roll credits.)

* "The Intersection of the Parallels" gives the Ninth Inspector a humourous but bittersweet farewell, as he speaks to an ascended Lily by opening a spatial gateway to say his final good-bye:
-->'''Lily:''' I'll never forget what happened today. \\
'''The Inspector:''' Oh, so you remember? \\
'''Lily:''' Either I've gone daft, or you were prancing around like a maniac. \\
'''The Inspector:''' Then you'd be wrong. I simply screamed and the Blorgons all jumped ship in terror. \\
'''Lily:''' I think I was lost. Hang on- I was in the Booth, and darkness swallowed me up. I remember clear as day! \\
''(A small current of blue energy pulses through the Inspector's palm, and he stares at it grimly)'' \\
'''The Inspector:''' Lily Taylor. Think of all the places we'll never see. Marzipan. I don't mean the sweet, I mean a whole planet. You'd probably despise it. Dreadful spot. There's these cats with no tongues. Who knows what got them? ''(laughs awkwardly)''..... I could tell that joke late into night over and over, and the crickets would die of boredom. \\
'''Lily:''' But, couldn't we go anyway? \\
'''The Inspector:''' Perhaps we could, and perchance I could. Unfortunately, it will be different. \\
'''Lily:''' Oh, no... I think I get what you're playing at. \\
'''The Inspector:''' I may not be capable of playing, period, depending on what happens next. I'm worried I'll have multiple butt cracks, or no butt crack at all. I fear what would happen if I had no butt crack. ''({{Beat}})'' [[DidIJustSayThatOutLoud Please spare me the details on how stuffed on me own sod I'd be]].... It's a clean and simple procedure. I get a glimpse of what I'm about to turn into. Until the amnesia hits. \\
''(The Inspector doubles back in anguish with a flash of blue light briefly erupting from his body.)'' \\
'''Lily:''' Inspector! \\
'''The Inspector:''' Step back, Lily! I don't want you to get hurt! \\
'''Lily:''' Inspector, are you dying on me!? \\
'''The Inspector:''' I drew in the full power of the Space Parabola. Anyone can tap it to heal themselves, but you can only handle so much. My body is being forced to make new cells too fast and it's disrupting the natural progression of my biological processes. They're utterly knackered now. \\
'''Lily:''' But surely you can fix this... can't you? \\
'''The Inspector:''' Well, that's just it. I'm already fixing it as we speak. Infinity Knights posses this big gimmick; it's what we consider as a way of redeeming more life. However, this means I'm going to be altered quite a bit, and as you might suspect, the side effects are often jarring. Sorry... I can't stay as I am now. No longer as my present self. No more innings with this wily semi-mint mug of mine. So when I depart- \\
'''Lily:''' Cut that talk out. You're really scaring me... \\
'''The Inspector:''' Lily, forgive me. I have to depart. And when I do, please don't think of my exit as dreadful. You were far from dreadful to me. I think so much more of you than you give me credit for... I wish I could say the same of myself... Honestly? I think I could have been a little better. ''(smiles meekly and closes his eyes, bracing for the change)''\\
''(The Inspector hunches over the Booth and blue flames envelop his body. He metamorphosizes into the form of a tall black man with a bald head)'' \\
'''The Tenth Inspector:''' ''Hola.'' Dread- Wow. Fresh skin colour- it's all dark this time. How unusual. Well, where did I leave off? If I'm correct... Marzipan! \\
''(Lily stares at the new Inspector dumbfounded as he gives her a puzzled frown as to why she's not reacting positively to his metamorphosis)''
