Hi, this is my first post guys so be nice. Some things bother me. First, maybe this guy (and I am assuming) was like, "If I do this now, they will assume this is a runaway bride and it will buy me time" kind of thing. Second, and this is the reason I signed up on Websleuths in the first place, how do we know that Annie did not take the transit to her office and leave her office to visit the lab for a moment? Perhaps she was supposed to be the TA in Bennet's class at 10:30. That would prompt him to teach the class on his own and notify the dean that she did not show up for work. I was a TA and it was a "paid job" in that it paid a small amount and I got college credit. I never heard of a lab job for pay in college but that does not mean it didn't happen.
At 10:00? I run over to the lab (that's why I left all my personal things in my office at Sterling) and will be back in time for my paid job with Bennett at 10:30. I didn't show up.
Just a thought.
