You know you went "D'awwww" during the scene where Tear comes outside to find Recette making the sign for the store and sees she named the store after both of them, even though Recette has good reason to distrust Tear. Why'd she do it? Because they're partners! In general, Recette's unwavering trust in Tear tends to produce one of these any time somebody else questions Tear's motives.
Particularly the second meeting with Griff.
Recette: Okay, so there's a lot of stuff that I don't get, like why the sky is blue, why garlic smells bad or why lemon candy makes you pucker up! But I know more about Tear than you do! A LOT more!

NONE OF IT, YOU HEAR?!

"I like shopping." Especially since this is the first time Arma lets herself admit she can 'like' anything.

Griff: Hm. It seems my exile won't be dull, at least...
