The other unidentifiable noise sounded again, and Bucky saw ice creep across the wall across from the slits in their door. Snart's ice weapon, then - the one he'd dropped when they fell. One of his friends must have picked it up.

Bucky wasn't entirely surprised when it was the masked James who appeared at the door a moment later. "Back up," he ordered them. "I'll freeze the door off."
