Robin and Finney are dating, which is cool. Robin is Finney’s romantic boyfriend, so he gets to hold Finney’s hand and listen to him talk about space and go on dates and stuff. This means Robin is Gwen’s platonic boyfriend, so he has gets to hold Gwen’s bag and listen to her talk about her friends and have her be the third wheel on dates and stuff.
Or, a bunch of head canons with Gwen both ruining and supporting Robin/Finney
Finney patching Robin up after a fight and Robin making comments about how he has the cutest nurse, but Finney is still mad at him for fighting.
Robin arguing that Finney can’t be mad at him, Robin got in the fight for defending Gwen against some kids who said she was weird
Finney pointing out that if Robin was defending Gwen, she is going to be more pissed than he is. Gwen likes to fight her own battles, she doesn’t let other people be her voice.
Robin realizing, oh shit, he’s right, and asking Finney to lie and say Robin got in the fight defending Finney because yeah Gwen is younger and shorter and smaller, but Robin is not prepared to be on her bad side
Robin’s uncle lets him take his truck to the drive ins on weekends, which is dark and secluded and if they see a scary movie, Finney will practically be in his lap the whole time
he arrives at the Blake house to pick up his boyfriend and is shocked and confused for Gwen to climb in the truck beside Finney
Finney is just like ‘Gwen wants to see this movie too, so I invited her’
Robin is a good boyfriend and he does actually like Gwen, so of course he has no problem with it, even if his plans are ruined.
Part way through the movie, Robin slips her some money and tells her to go get some snacks
And Gwen is smart and says ‘why? so you can be alone with my brother and make out?’
And Robin, completely serious, saying ‘yes, so make sure you take your time because you don’t want to see this’
Finney is just a flustered mess
Yeah, Robin is Finney’s boyfriend, but the match to his BFF bracelet belongs to Gwen
Gwen starts dating a boy and swooning over him, so Finney gives his best big brother talk of ‘if you hurt her, I will be very disappointed in you and I will make you feel bad’
And Robin’s like ‘good job, babe, you really scared that dude’
But when Finney’s back is turned, Robin is grabbing the guys shirt and promising to break his teeth if he ever hurts Gwen.
Way more invested in Gwen’s stories about the girls in her class and her bitch teacher and how dumb boys are than Finney is. Finney listens because he loves his sister and wants her to have a safe place to talk, but Robin listens because he loves girl talk and there’s no way Susie actually made out with Bobby while she was dating Jack, omg, what happened after that???
Gwen making up total lies to get out of the house when Robin comes over because she’s a good wingwoman and lets them have alone time
Braid twins as Finney makes dinner for all of them.
Teaching Gwen one on one how to do a round house kick so she can use her fists and rocks and feet
(does the same thing with Finn, but it takes way longer because Robin keeps flirting with him)
Also teaches Gwen how to swear in Spanish after she gets detention for the 12000th time for calling her teacher a fuckwad
Gwen helps Robin plan out dates. She points out the restaurants Finney wants to try and the new rocket launcher he’s been eyeing and the new rom com he hasn’t seen yet and if they go to the park at night, Finney will be able to point out the constellations as they hold hands under the stars
Robin is Gwen’s platonic boyfriend, the end.
Might turn this into a fluffy fic after I’m done with my angsty fic
