Thanks Phee for the screen shots and pointing out the whole but did you noticed the back ground I think that is Emma’s apt.
If it was hanging in Emma’s own apartment window and is something she sees every day, it would make no sense that she’s looking at it now all wide eyed and mouth agape like it’s something from a past life that she hasn’t seen in ages. It would make no sense to me for Emma to have the dream catcher in her apartment anyway. We know it was Neal who had kept it, and though Emma got new memories, history didn’t change, so Neal is still the one who kept the dream catcher, and it’s still always been in his apartment. Also, if it were something hanging in Emma’s own apartment, we’d have seen a shot of it at the end of 311, but we didn’t.
The most logical explanation IMO is that Hook gives her Neal’s address, and she goes there, (we can have a parallel shot of her picking the lock, to go with how Rumple picked the lock in Manhattan), sees their old dream catcher, and that’s part of what makes her believe that Hook isn’t just a raving loon, he is actually someone who knows Neal, so perhaps she should listen to what he’s got to say after all.
