How do I get Eva to say: "Manny, what are you doing?" And get him to reply with something about elevator tests?
Walk right up to the elevator door that faces Eva's desk (it may work with the other one, I don't know). When the door open, walk right up to edge of the elevator doorway, blocking the door and stopping it from closing. Then you sit and wait, it may take a few minutes to work.
Doomo Arigatoo gozaimasu, senpai!
