Well, being interrupted is one way to drop the subject, huh. Because at first Ange dismissed the movement of the sand as just an effect of Steven kicking it up, but it's pretty much impossible for it to start forming a sandcastle by itself.

It's so close to where he's standing too. And while Ange likes to act all cool and uncaring, worry does immediately set in when she sees it.

"Steven, watch out!" She's already running as she says it, pushing him out of the way of the sandbox. But as they land, the scenery around them has already changed - they're in the witch's dimension.
