I can't believe no one said anything about it. Why did she say she didn't recognise him because he grew up, he's not much different from his flashback version.
@nfzeta: They call this "informed attribute". What we see isn't necessarily what she sees. Alternatively, his flashbacks aren't accurate regarding what he looked like, because his own memories are by his admission fuzzy, thus his mind fills in the gaps with what it knows.
