(For @sih, who was asking for Finnrey positivity.)
For me, the proof of Finn and Rey’s connection is in their expressions. Every single time they look at each other, intense emotion is being exchanged. There’s attraction (the heart-eyes Rey gives Finn when he tells her he’s with the Resistance), shared joy (after their escape on the falcon), trust (always), longing (their parting scene in Maz’s castle), fear (whenever the other is in danger), protection (when they rescue each other and reunite), heartbreak (Rey crying over Finn’s body) and gentle affection (the Forehead Kiss™.)
Finn and Rey go through so much together, and they’re active and alive for every second of it. They’re never apathetic towards the other, and they never take each other for granted.
So that’s my take on it. When it comes to Finn and Rey’s love, their faces say it all.
