Fun fact: Klein got actually interested in that room because he overheard a janitor that was complaining that he is not allowed to clean that room and that makes him feel he's not doing 100% his job. The initial response from some higher ups was that the room will become a new janitor closet but months went by and then these reinforce bars were installed overnight. That persuaded Klein to continue his research.

PS. The room still exists and continue to serve its purpose.
