so based off the no labels answer he gave, i guess the tweet from the other week must've been referring to gar and not himself. he wouldn't say "laughs in bi" if he prefers to go unlabeled(which btw, in this day and age where tons of young male celebs and influencers try to be ambiguous about their sexuality because they know it gets them attention, it's hard to tell if wanting to be unlabeled is just that same type of bait or him saying he's not straight).
if that's the case, i wonder what'll happen in this season to show gar is bi. is it that him being the only want to save jason and bring him back home a hint that he's in love with jason? or is it that with tim now being canonically bi in the comics, and the show having introduced tim drake, tim and gar end up in a relationship?
and yeah, i agree, the mustache does look really good on him. i still prefer him without it, but he can pull it off pretty well
