Jack just got back with Castiel from a hunt, there were other angels after them and he looked to be in bad shape as he entered your room, his back was scratched up, and dried blood and dirt was all over it.

"Can you help me with this?" He looked at you with pleading eyes, letting his wings stretch out for you, they were large, bigger than an archangel's, and they were covered in blood and cuts.

"Castiel told me that...our wings are sensitive, and we should only let someone we trust touch them, i trust you."
