Regina's seemingly strong dislike of Emma:
"It was never a personal hatred Regina had for Emma, she was a threat. Regina wanted to stop her from taking Henry. She did extreme things to stop this extreme threat of losing her son for good. It wasn't a personal vendetta, but it was the risk of losing the thing that meant everything to her, Henry."
"Now that she is working with Emma, Hook (and the Charmings) to get Henry back. Regina & Emma call themselves "the Moms" and it's in a more friendly way. They're getting along.
"Soon they'll be an episode where Regina will help Emma with her magic. She is slightly impatient, but she is likely enjoying the interaction with her, unlike with the Charmings."
In Neverland, Regina and Emma have become downright friendly. "a lot of their baggage falls away, and they are just two women who want to save their child," Morrison told TODAY. "And there are moments of friendship, there are moments of very powerful foresight into how to be powerful together, and there are definitely things for them to learn from each other."
"By episode six, Regina will eventually give up on trying to convince the Charmings to do things her way. Will the Charmings' infuriatingly optimistic ways rub off on her? NO WAY! She laughs. Regina will have no choice but to stick with them until the very long #SaveHenry, Neverland adventure is over!"
Lana also notes that Regina does NOT fear Pan whatsoever. (She should because Rumple certainly does!) She has no idea how powerful he is....yet.
