Crowning Moment of Awesome: Subaru has three of these back-to-back. Ambushing Vita by crashing through a building, catching her weapon mid-attack so the Chivits could tag her out and ending it all by stopping Nanoha's Divine Buster Extension with a punch.
Crowning Moment of Heartwarming: While she definitely is a source for a lot of humour in the series, the fact that Precia in this continuity is a genuinely Doting Parent towards Fate is definitely a source of warm and fuzzy feelings for anyone who hoped that Fate had a happier childhood in the main series. The fact that Precia is good friends with Lindy and Alicia is also alive means that both of Fate's families can be together and happy this time around.
Another bit of heartwarming comes when we see Due, renamed Nino, alive and interacting with the younger sisters of the Nakajima family considering her fate in the main series. And she's every bit as kind and like an older sister as Quattro in the main series says she was, albeit slightly more mischievous.
Jail is still just as much of a nutcase as he is in the main series, but this time around he's only a villain in the roleplaying sense and at the end of the day it's all in playful fun. Whenever he's off-duty, he is a caring father to his daughters and a Cool Uncle to the Nakajimas by virtue of him being Quint's older brother. Whereas in the main series it's ambiguous as to how much he actually cared about the Numbers, the affection he shows here seems to be genuine, although at times he still gets carried away and lets his experiments get in the way of his family's safety.
