What is up with this?

So I went to the movies last night with Brianne, Megan, Jason, and McNamara. Last time I went to a movie w/ him (yes, I still like, him so shove it) he was sitting next to me but went to get popcorn and Megan stole his seat. When he got back he was really pissed at her, but I assumed that he was mad because that seat was closer to the middle. Then this time he did the same thing (sitting next to me) and before he went to get popcorn he was like "okay, seriously, this is my seat. megan if you take my seat then I'm going to kill you" which was weird because Megan's seat was closer to the middle than his. When he got back he ended up (somehow) with his arm around me. It remained there for the entire movie (I was worried that it might fall asleep >.<) until I went to the bathroom (I went a. because I had to pee terribly and b. to give him a chance to remove his arm without being awkward). When I got back, not only was the arm replaced but he also put up the arm rest in between us and, in an amazing imitation of the 7th grade couple in front of us, I ended up pulled to him with my head on his shoulder (and getting huggles during all the stupid parts of the movie). After it was over we went to Starbucks and there was a steady stream of his slightly awkward sex jokes (the ones you always assume he makes at everyone) directed solely at me... I'm starting to think maybe (just maybe) he likes me... Also I couldn't sleep until 5 in the morning because my dad was running a virus scan on my computer and now I'm sooooo tired... ya... :D
