Professor Hipster's level of professionalism leaves much to be desired. Button your shirt. Stop drinking with your students at a frat party. Don't casually refer to yourself as Indiana Jones. So far, I am only impressed by his scene at the end of the episode.
What's with the suddenly indiscrete blood consumption? First, Elena's sucking on a blood bag in front of a church in Memorial. Now she's about to bite a college kid in the middle of the quad during the day. And speaking of the quad, I'm pretty sure Damon parked his car on the sidewalk.
Elena is moralistic enough to punish "roofie guy" by feeding on him. However, no one prevents the girl from drinking the roofied cup. Oh man. Be safe, party extra!
