Hindsight's twenty-twenty, but Clarisse never expected Barrow to actually bust the door off its hinges. The guy is strong as hell, sure, but those doors are heavy. If she knew what was about to happen, she would have shifted several feet in either direction until she was completely out of the path of destruction.

But she doesn't know, so when the door comes flying off its frame with Barrow's entire weight behind it, she doesn't even get a second to think whoops or oh shit before it hits her. A corner of the wooden door clips her right on the side of the head, and she crumples to the floor like someone's flipped a switch off. Bam.
