Seeing Woolf befriend a dying Veigan soldier in Episode 15 is this and a massive Tear Jerker at the same time.
Asemu being supported by the school bully -- some time after saving his life -- at graduation in episode 18.
There's also the part where Asemu stands up for Zeheart when the Federation MPs (correctly) accuse him of being a Vagan spy. Even Zeheart is shocked at how quickly Asemu stepped up to defend him.
When Asemu is dejected upon learning he has little X-Rounder aptitude--and thus is not as good as his father--Woolf takes him on a little trip off-base to meet Mardona's son, Rody, who offers a much healthier viewpoint on being the "Well Done, Son" Guy. Woolf then tells Asemu explicitly that he is not Flit and that's nothing to be ashamed of--being Asemu is pretty good too.
When Grodek is released from prison 25 years later, he is saluted as a true unsung hero by the entire guard.
In the same episode Woolf and Captain Alloy share a nice moment. The Relationship Upgrade might not be confirmed, but they're certainly more comfortable with eachother.
Everything about Obright and Remi. Everything.Except Episode 27....
Episode 27. Asemu and Zeheart come to an understanding and renew their friendship as they both attempt to destroy the Downes battleship that is soon to collide with Earth.
There's also a villainous example, where Zeheart is falling into Earth's atmosphere, but is saved by Dole. Dole, who never really agreed with Zeheart as a leader, sacrifices himself by using his own mobile suit as a heat shield to protect Zeheart. He tells Zeheart that he was inspired by Zeheart's vision to create a utopia for Vagan.
In episode 28, Asemu wears Woolf's signature jacket and even paints the AGE-2 white in honor of his mentor.
Episode 29: "Nice to meet you, Gundam." There's just something about the way Kio says it.
Episode 34: Asemu returns and tests the diva crew only to have his challenge interuppted by the Vegan he saves Kio from a Vegan unit with the very same move that killed Woolf saving him serving as Fridge Brilliance and a heart warming Call Back as well as he fufills his mentors last request to surpass him.
