Y'all have some brave characters the only character I have that would do anything of the sort is Hunter and really he's a terrible person and would either kill you or enslave your mind if you tried anything although he is trying to take over the world using his siblings so I suppose he wouldn't want to admit that
Sam would rather die than tell that the only reason he became a superhero is out of nostalgia
Jalen would rather die than tell (i dunno he's kinda open)
Ellie would rather die than tell Sam that she dyes her hair and only became "grunge" for another boy
Alice would rather die than confess to Sam
Floyd would rather die than tell anyone that he sometimes get PTSD and major panic attacks due to the Civil War
Cameron would rather die than tell Sam that he got him his 14th birthday present from the trash
