I am doubting the younger version of Snow Queen, simply because when she first appeared to Elsa in the Past, she was already as we see her in SB today. So unless a powerful anti-aging spell was in effect, and could withstand being in the LWM, I don't think we'll be seeing a young Snow Queen.

The young girl was in Ep 3.21, and I believe the actress' name is Abby Ross. She will be reprising her role as young Emma for the upcoming episode, so I think you're observation about Emma having something meaningful happen during this time is spot on.

I am very curious to see how they resolve that question of how the Snow Queen and Emma are tied together. We probably won't find out for a couple of more episodes, though.
