Saerian stood, watching the wall create itself, brick by brick, piece by piece. It was taller than he was, and it was thick. All things considered, it was impressive--especially since when he'd last seen Jo, she'd had no idea how to do this (at least, not that he'd seen).
He could climb the wall, easily. But Saerian instead went with a different tactic.
Distraction.
For a split second, he let her dream bleed into Dean's. Just a little. Just enough so that, behind that wall, she could see what he was facing.
