Here my theory:

The Snow Queen has always been alone and rejected by everyone thanks to her powers. She said it: she wants people who love her, a family. In the last ep, she seems to use mirrors in order to capture some portions of souls. What if she traps a conscience in the mirror, like that she can give a new conscience to someone... in order to force this person to love her.

Remember when she presented herself to Elsa? She said she was her aunt, but Elsa's mom never talked about her before. i think it is because the Queen of Arendelle was a victim of the Snow Queen: she could try to force her to become her sister, to love her. The curse on the Queen must have been broken; that's why she never mentionned her -> Ingrid is not really her sister cos she was cursed, but for Ingrid; it was real cos she was loved.

After this failure, she could have been put in the urn. Then, she tried to do the same with Elsa/Anna in the past, but she failed (cf summary of 408) = she put Elsa in the urn and captured/killed Anna. In the promo pics of 406, she has the box of the Sorcerer's hat. She probably gave it back to Rumple, who told her the (future) existence of the Savior, a really powerful person with a lot of magic. I think her plan is simply to force Emma to love her, to force her to become a part of her family. And i'm pretty sure her big mirror is one of the keys of her plan :)
