I don’t know…I kind of think that Emma sees a little of her own desperation in Gold, afterall it wasn’t long ago she was fighting to get her own son back and then fighting to get back to him from FTL when she and MM went through the hat.
I think this trip may bring a kind of understanding on Emma’s part of where Gold is coming from…I mean she could ask herself just how far she could be willing to go to find Henry if she had lost him in the same way as Gold lost Bae. Not saying they are going to be BFF’s by any means but I think she’s going to see him in a different light.
And I may be in the minority here but I think because she understands how important it is for a parent to have their kid in their life she might even help Neal/Bae to at least talk to Gold (unless I’m completely wrong and she springs Gold on him by “turning him in” like the Charlie’s Girl song said in Broken.)
