I had two people tbagging at the hatch (one had a key). Either the key person screwed up (waited too long), the other survivor screwed up (didn't hit the button to hatch escape quick enough), or the animation screwed up but I downed the one without a key, the hatch opens and the key person jumps in but I closed it before downed person could jump in.

It was great. Hooking them was a great joy bringer, even if only one clown got punished for their pride
