Does my best friend like me?

I'm a 16 year old guy and so is he. Besides our hands accidently brushing about 50 times a month, he seems to be defensive for me. We went on a field trip over night with four guys to a room (we were in the same one). This guy named Tim was bitching about comforts and took one of two queen size beds while my best friend and a mutual friend shared the other. I didn't care because I hate Tim so I slep on the floor (its actually something I'm used to).

Then my best friend (let's just call him Dan) got all guilty that I was on the floor and offered to make room for three people, but I declined. He suddenly got all mad at Tim, arguing with his bitchiness and ignoring his bratty demands like shutting the lights off when he was the only one going to go to sleep the early. This was unusual for Dan, since he never had any problem with Tim before this. He then sent an extremely angry and funny text to his girlfriend about Tim's bitchiness and that Tim's girlfriend broke up with him because he couldn't get a broom out of his ***. Dan has also has been growing apart from his gf and simotaniously, as it seems, has been hanging out with me more.

I know he's at least being an amazing friend, but do you think there's something more? I wouldn't mind, I just don't know if he's hinting and waiting for me to notice and make a move. He's also been teasing me with a lot of my other friends who are girls about my *** (it's huge). What do you think?
