He can see the moment of recognition in her eyes, and he knows that she knows who he is, but he can also see the look of horror on her face and his instinct is to take a step back. She'd pushed him away once, he's not sure he can live through that again, and not now, even if it isn't real. Looking like he does, remembering all too well how she'd said goodbye with such finality, he's not sure her approaching him is a good thing.

His knees are feeling weak, and he puts one hand against the wall for support, noting belatedly that there doesn't seem to be a door where he walked in. But even though he can only brace himself for more heartache here, even if the door was there, he knows he wouldn't go back. That even though seeing Kim hurts so much, he can't help but look back, after so long wishing he could see her again.
