The way the two of them interacted in the snow cave e fastest we have seen Emma let down her walls. Talking a to perfect stranger who had as good as condemned her to death she is sharing her lack of magic control, growing up alone and talking about Henry.
I just watched the episode and I think this probably the only thing that bothered me.
It’s that Emma never mentioned that she had a son to Elsa, so where did that come from? I feel like there might be another deleted scene there when Elsa tries to get Emma to talk about herself ad she mentions Henry. But I don’t remember Emma talking about Henry to Elsa.
