I think she's hallucinating her past - like seeing her reflection in the window a couple of issues back. Combined with her nightmare in the guest page, Danielle seems to be having a very rough go of things. Especially given the title of the issue - is she a madwoman in a cage?
My supposition: her current programming is somehow in conflict with her previous programming, and this is a form of memory 'bleed'. I think the two last frames are meant to insinuate that the similar situation - hand poses, bird cage, etc. - acts as a trigger for the hallucination. I don't think Jeane is someone else.
I'm with Werdna on this one and wishing there were a like button in the menu.
I'd almost hoped that there would have been a view of Danielle's eyes in wide shock/panic after the last panel. Though I understand leaving it to our imaginations (and you've seen how vast and vivid those can be) to fill in that reaction gap was easier and more effective.
Though in contrast to Werdna, My thought on the whole flashback thing is more pedestrian; in that maybe Danielle's mind just needed time to heal, much like Adrian's heart did before he started playing guitar with Erin. .. Or maybe Danielle has just been licking too many stamps on both sides.
