Strip 1889. You just walked in on the guy your roommate hooked up with dancing around your apartment with nothing on but a condom? Yes, the proper reaction is to put up a banner, get some party hats, and throw confetti.
Momo's new chassis. Judging by the nosebleed, Marigold is going to be eating ramen for longer than she lets on to pay it off. It establishes Momo is more than some kind of surrogate pet/comic relief character (the way Pintsize or Winslow are usually portrayed); Marigold cares for her pretty deeply.
Not only was this just in time for Christmas, but Jeph actually wrote the entire fictional speech, of which he only used an excerpt in the comic, which somehow makes it even more heartwarming. It can be found here.
Double CMoH; The AI on Hannelore's Dad's space station apologizes to someone he played a cruel prank on by giving her some shares in Ellicott-Chatham Technologies. The fact that he owns shares in the first place reminds us that AIs really are humanity's equals. The second part comes when he says the shares she now owns are worth 4.6 Million US Dollars. Her ponytail comes undone from the shock.
Hannelore's words of encouragement to Marigold. They become even more touching in retrospect as the next few strips show how much Hannelore is speaking from her own heart about having come through to the other side of that day herself.
Someday, everything is going to go right for you, and it will be so wonderful you won't even know what to do.
And in a meta-example, the fan response to it and Jeph's reaction to it, especially considering it occurred about a week after he'd had a Creator Breakdown due to Fan Dumb.
Jeph's Twitter: I wish I could share some of the emails I'm getting about Claire with you guys. They are amazing.
And later, after getting an email about how QC has an "agenda" now,
Jeph's Twitter: Also got literally 1500+ emails expressing happiness about recent QC events so I guess PROJECT AGENDA is working.
Pintsize tells Momo that he was Marten's only friend for two years before he met Steve and Faye, and that he's happy that Marten has friends and a life now. He even tells Momo that there are different ways for them to do their jobs. Of course, he won't tell Marten that, as he defaults to his normal behavior when Marten asks what's up.
What started as a throwaway gag earlier on in the story evolved into a rather touching moment. Marten's dads' (yes, plural) wedding arc culminated in Martin's Mom delivering a rather heartwarming speech during the dinner showing that there is no love lost between them.
Blogpost for comic 2510: Jeph links to his first kickstarter for a Deathmøle album with a goal for $9,500 in one month. Blogpost for comic 2511: goal has already made its goal and then some: 38,911
Jeph's: Holy CRAP you guys, the response to the Deathmøle Kickstarter has been WAY bigger than I had ever dared hope! We're over 300% funded 24 hours in, which is AMAZING. Thank you so much! But it is not over yet! We are hammering out some extremely cool stretch goals and should be posting them in the next day or two, so keep your eyes peeled. Thank you, again, for your support. I am tremendously thankful.
It's a mix between this and a tearjerker, but Dora is willing to have the insurance company pay for Faye's alcohol-related breakdown. Why is it still a tearjerker? Because Dora is still firing her, and is still too upset from their last encounter to tell Faye in person. So she leaves it to Hannelore.
"You're beautiful." Even more so considering how often the bodies of transgender people and the reaction to them are used as a cheap punchline/source of disgust.
In the wake of Faye getting fired, Pintsize helps her get a job completely unasked for. Sure, it's a job fixing contestants in a semi-illegal robot fighting ring, but the fact that he cares enough to offer his help without any of his usual joking around is remarkably reminiscent of the first example on this page.
Dora finally makes some amends with Sven. Doubles as an awesome moment for Dora because it's a change in her attitude: She realizes that you can't just give so many strikes to throw somebody out, so she's resolved to have them work together to become better people.
Faye's entire relationship with Bubbles is very sweet: a chronically sarcastic Recovered Addict with intimacy problems goes all out to make friends with the only character in the strip with a darker and more troubled past than her own.
Bubbles describing the terrifying consequences of zombie AI and then reassuring Faye that she's on the good guys's side.
Bubbles: And if it comes down to it, you may count on me to stand on the front line to protect you. ...That is, to protect "you" in the sense of all humanity. Although you are small enough that you could probably shelter behind me. There would be a risk of flanking attacks, but with adequate defilade–
While their introduction is creepy and dramatic, Spookybot takes a quick moment to compliment Bubbles' name, which is especially sweet because she keeps it in honor of her squad members.
Bubbles and Faye have a hug after Bubbles has admitted "your friendship was the sole source of joy in the final part of my existence". Faye is actually crying. Immediately downplayed:
Spookybot: [frowning] How touching. We have never vomited before, but this may inspire us.
Emily: You should try it sometimes! It's a very intense experience.
Although it's in the wake of the tragic revelation that Bubbles' memories have been lost for good, the mysterious AI gets some for encouraging the gang to support Bubbles and reminding her that she has friends who care for and love her.
When Bubbles is discussing the idea of Spookybot with Station, the latter mentions that they might be able to eavesdrop on any AI communication. So Bubbles takes the chance that they are to thank them through Station. It works.
