Cho passes her bag through, with Faolan safely inside, then her weapons. Then she slowly starts to work her own way through the hole, balancing and stretching and twisting around until both her legs are on the other side and her back is resting on the ice, hands still pouring magic into it. "Sif? When I say go, I want you to pull me through as quickly as you can."

The ice will begin to close the moment she takes her hands from it, and she doesn't exactly have the leverage to guarantee that all of her is through to the other side before that happens. "Ready? Go!" As soon as she says it, she sticks her arms out above her head so that Sif only has to pull her straight through.
