Bucky nodded, suddenly for the idea. Perhaps not a henna tattoo on his arm but something painted over the red star on his arm, that he would welcome. That star meant nothing to him, a symbol of a bygone state, put there to mislead anyone who glimpsed the Winter Soldier and survived. The whole arm was, really, but if he changed that perhaps it could feel more comfortably his after all.

"I'd like that, Aang. You can paint it over the star." while it would only last until he resurrected again, Bucky liked the idea and it could always be painted again after. It could even be something different then, a visible statement that HYDRA didn't own him anymore.

Yeah, he likes that idea a lot.
