to be fair we still don't know if Shiro has any romantic feelings towards anyone since he has no love intrest, if he ever gets one it'll probably be a woman though
and I dunno what their plans with Pidge are
frankly at this point the only 3 characters I still like are Allura, Shiro and Hunk, because they've been fully fleshed out from the beginning and with the exception of Shiro on some small level, the three of them weren't used for blatant queerbaiting
basically we know Shiro was kidnapped and has a dark mysterious past but has a paternal instinct
we know Allura is a sassy British alien princess who has situational racism against all Galrans
and we know Hunk is Fat and a baby
all we know about Lance is that he looooves the ladies, and for similar reasons to making a character being gay the only focus of their character, making wanting to fuck girls Lance's entire character, is bad writing
what we know about Pidge is that she got kicked out of the galaxy Garrison for being a bit too correct in her conspiracy theories about her Brother.....so she stole her brother's clothes and pretended to be a dude so she could continue her investigation(even though that wouldn't have worked if they did any sort of blood or urine testing since it would match her dna...not to mention she'd have to figure out some way to conceal her menstrual cycle to keep the facade of being a boy up), otherwise there isn't much to her
Keith we now know is a galran hybrid, is hetero, and has feelings for Allura....again that's about it, and also he apparently thinks pining romantically for another guy is how you express brotherly affection (if he and Shiro were supposed to seem "brotherly" they coulda' fooled me)
and Coran is just comic relief so he has very little character to begin with
also Hunk fell in love with that Alien girl remember?
