The Trailer For Frozen 2 Left Us With a LOT of Questions — Here Are Our Theories

Kristoff manages to snatch Anna away from the growing flames, which leaves Elsa and Olaf trapped in the middle of what looks like a heart-shaped ring of fire.

Nonetheless, Elsa attempts to put the fire out with her ice, though it doesn't appear to do much. We can't help but think someone created the fire to trap them — maybe the beings who are causing all this ruckus in Arendelle to begin with?
