There is a prince at the bar, penning a note. It's short and simple, and Bar gives the instructions of, "Give this to my... give this to people who would care." If he says it's for his 'friends', people like Katara and Toph may not get it. On the other hand, if he doesn't...
He is looking worlds better-- but the curse has taken it's toll. Color is better, his eyes aren't marked by deep smudges of shadow from lack of sleep, and his posture is relaxed. He has a small, simple meal on the bar (broth, rice, a few shreds of meat with a mild sauce).
He writes
I'm going to be fine. You can stop worrying now. Thank you. -- Li He almost doesn't sign it. He's not sure what name he should put down. But he goes ahead and puts what is safe...
Even if he realizes he may never be that person, or the person he was -- he's not sure who he is, really.
His body is mended, but his heart is still heavy. He sits, and begins to eat quietly, picking at his food with little enthusiasm. But at least he can eat, and he needs to. So he does what he has to, like he always has.
