FINN: Now that was some flying! How did you do that? No one trained you? No one? That was amazing! You set me up for it! That was pretty good.
REY (simultaneously): Good shooting! Thanks! I—I don't know!—I've flown some ships, but I've never left the planet! Your last shot was dead on. You got him with one blast! It was perfect!
This is one of those moments that we live for in Star Wars: these two just doing the kind of goofy, spontaneous things that friends do. There's a rule in screenwriting: show, don't tell. This is showing a friendship instead of just telling us that they're friends.
Quote #5
REY: You have to keep going, stay out of sight. I'll try to fight 'em off.
Rey is mirroring Poe's words to BB-8 at the beginning of the film, and it's another sign that she's more than just an owner.
Quote #6
FINN: That's where my friend was taken. I've got to get there, fast!
Now, here's a good friend: the whole galaxy is at stake, with planets blowing up and whatnot, and he's only interested in getting his buddy back. Funny thing about Star Wars: saving a friend often means saving the galaxy, too.
