Now Finn is out of the First Order, he's allowing himself to be human for the first time, with feelings and desires etc. The one big feeling he keeps coming back to is how attractive everyone around him is, now he's let himself notice.

Rey, super cute, could kick his ass without blinking.
General Organa, powerful, smart, absolutely stunning even now.
Poe, cocky, cute curly hair, sinful smirk.
