blaintana has unbelievable potential because santana views blaine as this lil freak thang who happens to be her friend's weird boyfriend and looks out for him like a little brother. it's amazing
a few reasons why blaine/jake would make a good couple
pretty chill x super dramatic THATS AN AMAZING DYNAMIC???? like jake's just like 😳 to all of blaine's shenanigans but he ends up going along with them (puppet master, the back corner)
bonding over having older half-brothers they've never been close to, but are starting to become friends with (and yes, cooper is blaine's half-brother since he's fully white and blaine's half white)
blaine appreciates this man's talent have you seen his reactions to jake's performances??
serenading each other with all the little bleacher-guitar stuff that blaine would LOVE and the courtyard stuff even if i don't think that'll be their exact place
they're both silly romantic guys
jake could help blaine be less uptight in a comfortable way (like skipping class to ride your scooter in the hallway) and blaine would probably try and make jake's life some more organized
this may sound weird but they kinda both have infidelity problems with sex and i feel like they wouldn't like inadvertently make each other feel neglected since that's where both of their cheating stemmed from
blaine likes people with layers and jake has plenty of those so he'd probably want to peel them back from that """bad boy""" persona jake has going on
they both have a bit of anger issues (blaine only in certain situations so moreso to jake since he has like fought with people more) but i feel like they would know what to do with each other. like blaine would need to punch a bag or sing for a while before being calmed down while jake would just need the holding back and calming down.
blaine's had to learn to channel his anger and he could teach jake too do the same.
that's all i can think of right now. all in all, they'd be good for each other
