Something had begun to nag at the back of Aang's mind. Something about the girl that seemed familiar, something more than just her arrow, but it's not until she looks at him that way that he knows what it is.

He's seen that kind of look before, but coming from blue eyes rather than brown.
And in that instant he knows exactly who she is, and goes so far as to bite the inside of his cheek to keep from laughing.

And then Sokka arrives unexpectedly. Aang is so surprised that that he bites down harder than he should have and regrets it instantly.

"....ow," he mutters as Sokka speaks. When Jinora turns to him he nods, and then reaches into his mouth to see if he's bleeding.

Nope. Not bleeding. Just...dang that hurt.

"You're...Ikk...no. You're Jinora, aren't you?"
The picture that Tenzin keeps with him is apparently out of date.
