Trapped and forced to listen to this HYDRA asshole's rambling. Why you're trapped is up to you, but in a glass cage you can't do much but sit back and try not to roll your eyes too much.

"HYDRA operates as a machine. Even one as insignificant as you would be able to see that. But... you are useful as one thing. An informant. A poker chip in my little game. Ja? So. Tell me what you know."
