A bit of an In-Universe example: In the Yogsquest Episode 8, shortly after Duncan killed Sjin's rat dad, Sjin's about to cast his only healing spell on its only charge, and casts it on Duncan, saying he forgives him.
In Hannah's playthrough of The Darkness II. "Remind me to let Dolfo shoot pigeons."
Pretty much any of Rythian's reactions to the treatment of Elizabeth in his Bioshock Infinite playthrough. In particular his utter rage at the scientists calling her a specimen. (Hell his reaction to pretty much any of the extreme Values Dissonance in that game.)
An example that relates to both the Yogscast as a whole, as well as to Area 11. When it was obvious that Sparkles* had drunk far too much for part of the livestream, Duncan and Strippin immediately volunteered to get him home. Sparkles* then gave Simon a very drunk hug after saying how much he loved him before being dragged home.
You are Awesome Zoey tells her story to show support for those who are bullied or depressed or have problems with their lives. Tearjerker meets Heartwarming meets Moment of Awesome. I defy you not to tear up a little when watching it.
Big Girl A song from Sips about how larger women generally hate themselves because they're not "thin" and "fit" and how they're absolutely wrongabout it. It can hit really close to home for some fans.
Although it takes a while to get there...
Their Dwarven Dairy Drive raised over $100,000 (Ł60,900) in their first day.
A lot of the donation messages are also heartwarming messages about how the Yogscast has got them through life, much to Sparkles* and Strippin's obvious happy surprise.
Day 28. The donations now stand at over a million dollars. A million US dollars. With the largest single donation standing at over fourteen thousand pounds.
Kim's song, So This Is Yogscast, in which she looks back on her first year working at the Yogscast. She sings about how she's very lucky to have all her friends beside her, while the video shows footage of her playing games and fooling around with other members. It was published on her birthday as well.
People being accepting of Zoey's girlfriend Fiona, who joined her on the livestream, and of Zoey reversing her decision to appear on facecam due to her anxiety.
An unexpected one in the How Do I Craft This Again? music video is that there's a distinct sense in certain parts of the film that many of Martyn's friends already know how to craft this stuff (Sjin, Lalna and Xephos being amongst them, and they're some of the most skilled Crafters in Yogtowers)... but they just don't have the heart to tell him and spoil his sense of achievement.
Christmas day of Hannnah's Advent calendar. Lewis gets her a present, aka, puts the last package wrapper over his head.
There's something sweet (and funny) about a lot of the nicknames Rythian chooses for the members of his XCOM crew named after his fellow members. Zoey gets "The Princess", and Nilesy is "Cara Mia" in a shout out to last year's live streams.
A surprising incident during the Charity livestream 2013, while reading out the donator comments. A Proposal. Spoilers: she said yes.
One that mixes with Crowning Moment of Sadness, The Last Rufus Blog. Hearing the normally calm Hybrid Panda choked up and just playing with his dog for one last time is both incredibly sad and incredibly cute/heartwarming at the same time.
Dave Chaos opens his space themed lootcrate with son, Jack. Cue adorable.
Nilesy tells one utterly bizarre yet strangely heart-warming story which may or may not be a dream on his part. The Yogscast have decided that each of them has to come up with a board game if they're going to die, so that their friends can play it to remember them. Dream or not, that's adorable.
Pretty much everything about Zoey playing Gone Home. Her Squees every time something romantic happens is just too adorable for words.
In the final battle against Lysandre in Pokémon X and Y, Zoeya chooses not to use Xerneas for it since she feels that it's had enough abuse and deserves some rest away. She also refers to it as a rescue rather than capturing it, saying she's here to help it and not to hurt it. Finally, she chooses to finish the fight with Chou, complete with flashback to him as a baby Chespin.
Any time Strippin and Dodger are onscreen together.
Episode 24 of Zoey's Tomodachi Life: Zoey's Mii proposes to Fiona's. Words can't describe the girls' reactions, to Fiona's jealousy of Sips' Mii (who wanted to ask out Zoey's) to them unable to stop blushing at the whole situation. It's difficult not to smile around these two in general.
