Oh my gosh, the idea of wrists and forearms having that kind of subsumed meaning is so, so great. There's something wonderfully vulnerable and kind of delicate about wrists in the first place, and combining that with the gesture of shedding your arms and armour before someone is just amazingly intimate.

(Also, omg, excuse my gushing, but ugh that Sanza brother fic is still the loveliest thing-- there's such a great sense of each other as one of the few constants in their lives, and the way that there are some things that need to be said out loud with them, and others that don't. Auuuugh I love it.)
