( Jo's eyebrows lift when he tells her that his real name is Miles. Whatever he's gone through, he clearly feels a disconnect between who he "is" now and who he is, as far as she can tell, so she nods to encourage him. If that's what he thinks he should do, then she thinks he should do it, too. Chances are, his instincts are correct, drunk or no. )

Maybe. I'll call you Miles if you want.

( Maybe she's misunderstanding, but maybe she isn't and maybe if even one person calls him by his real name, he can make himself into the person he wants to be, not the person Baby had become for, presumably, the adults around him. )

I think you should do what your heart tells you to do. That sounds corny, I know it does, but I really do believe that.
