I was probably the most excited that Poe lets Finn raid his closet. (And got the jacket fixed)
Coldatom hc: When Len is spending time with Mick, or someone else on the ship, (or just screwing around idk) Ray will raid his closet. Len's clothes are tight and a little too small on him, but it makes his muscles stand out. It doesn't "upset" Len, per se, more along the lines of... "Frustrate". Take that as you will.
