And on top of that, She was dangerous before she learned to control her power. Having control of that power actually makes her MORE dangerous. Particularly if something were to set her off, say trying to hurt Anna or Kristoff (who I presume is Anna's husband). Imagine the havoc Elsa could cause if she was really upset.

And I would imagine that being trapped in an urn for who knows how long might be cause for her to be just a wee bit upset. Hence the white out that i predict for SB.

And heaven help us if Elsa and Regina get into a spat. Fire and Ice don't really mix well.
