He can't possibly fit through there. Looking at the gap, he doubts if he can get his arm through up to the shoulder. It's a good thing Danny's not claustrophobic, although after this experience he might get that way. He fancies he can feel the press of walls of debris against his ribs every time he breathes in.

He can see pink, though, and even if he can't quite reach the children just yet, he can talk to them. Squirming as close as he can, he makes a tiny magelight right in the gap in the wall and gives a low whistle. "Hey, can anyone hear me? Your mum asked me to look for you. I'm gonna get you out, okay? Might take a little while, but..."

The debris creaks overhead, and his heart rate ramps up exponentially. He can put up a small shield if things really start to crumble, but it won't hold but so long.

On top of everything else, that means he's in a time crunch.

"If you can hear me, I need you to tell me if you can see anything around you."
