It's Anna! It's Elsa! It's another photo from Once Upon a Time Season 4.

Elsa has arrived on Once Upon a Time. This Frozen queen is played by Georgina Haig.

For some reason Marian doesn't look happy to be back. I'm guess she and Robin Hood have a lot to talk about.

It's Elsa and Kristoff! These Once Upon a Time characters are played by Georgina Haig and Scott Michael Foster.

This is unexpected. Robin Hood suddenly finds himself caught between his presumed dead wife Marian and his new love Regina. No doubt things will get messy.

We approve! Look at the uncanny resemblance between Georgina Haig and Queen Elsa from Frozen.

Any chance that Marian will tell Robin that his new love was actually the reason she "died" in another realm?

Georgina Haig is seen here playing the role of Queen Elsa on the Once Upon a Time Season 4 premiere. It's titled "A Tale of Two Sisters."

Emma thought she was doing the right thing not leaving Marian behind. Little did she know that her actions would ruin Regina's happy ending.

Yup, Frozen has come to Once Upon a Time. Check out this shot of Kristoff and Elsa on the Season 4 opener.

This is our first look at Georgina Haig as Elsa on Once Upon a Time. Pretty amazing resemblance, huh?

Is there any chance their newfound peace will hold and Regina will forgive Emma for ruining her happily ever after? We think the odds are slim.

Old friends return on the season 4 premiere of Once Upon a Time.

Will Else learn the secrets of her powers? Were her parents looking for answers when the died?

We have no idea what Hook and Emma are seeing but it obviously isn't good. Perhaps it's a snow monster from the world of Frozen.
