I’ve never really thought about this before but what if Lily was bisexual?
Lily being really annoyed at James flirting with her at the beginning of 5th year because he is objectively attractive but also really annoying and she’s confused about who she even likes.
Remus and Lily bumping into each other one night in the restricted section both searching for queer literature.
Everyone thinking Lily was being a goody-two-shoes by helping the head girl out constantly when she became a prefect but really she just has a massive crush on her.
Drunk Sirius and Lily discussing sexuality and just being like fuck it why is everyone so attractive pass me the vodka.
Lily making it extremely clear to James when they start dating that if he says something stupid like ‘does this mean you want a threesome’ she will curse him into next month.
Lily watching out for queer kids who are getting bullied and sending anyone bullying them straight to McGonagall.
Lily catching James staring at girls and saying ‘yeah she’s hot right?’ just to wind him up.
James commenting that he must be extra lucky if she chose him over all the other guys AND all the girls and Lily just shaking her head at him like ‘you are a prat it’s a good job you’re cute.’
