In Project Almanac, after David tries to "fix" something he returns to find things drastically changed. One of those things, which seemed curious to me, was Dr. Lou walking through the lobby carrying a box of what appeared to be his personal belongings, and David asks him where he is going, to which Dr. Lou replies (or something simliar to):
No need to be such a smartass, Mr. Raskin.
I took this to mean that something David did caused Dr. Lou to get fired. The group was able to trace all of the other differences to a couple specific events, and we see them do this. But is there any information as to what happened to Dr. Lou?
