HE WOULD BE DEVASTATED. Some of his most positive Aather experiences are when Dragonfly admitted to trusting him and he's cherished that and has done his damnedest not to break it ever since. OTOH he'd understand that it would be fully deserved, so he wouldn't hold it against Dragonfly as much as he would constantly beat himself up for it. Lately Kit has been feeling pretty decent about his place on the team and his ability to take care of Coral, especially since he hasn't had any major fuck ups for a pretty long time, so messing up that badly would take him back to the days when he felt like the WORST TEAMMATE who didn't know HOW TO TEAM and it would just. Be a pretty big backslide for him :'D

GOOD THING IT'S NOT CANON MAN, HUH.

... what would broken trust look like in a Hikaru heart game :U
