They sort of toss her into it head first, keeping her arms pinned to her sides so she can't push it away from her, and then they spend a few seconds folding her legs in behind her. It's obvious by now that talking doesn't work, so she just fights silently. She manages to give one of them a good stomp to the bridge of the nose, and both feels and hears the bone break, but the man doesn't react in any way, other than snapping his head back on impact. She's so busy watching him, waiting to see when he's going to figure out that his nose is broken and that she's responsible for it, that she stops kicking and flailing long enough to get all shoved into the cage. Then the door snaps shut.
