Why would he ask my friend about me?

So I'm a junior in high school and I just moved an hour away. I have liked this guy since freshman year and he was in my English class. We barely ever talked. Like I would say hi to him and stuff but that's it. Also my coach was his spanish teacher so whenever I would walk into his class he would like yell my name and I was just like OK hi. So I moved and I talked to him on fb and told him I moved but then I had to go. The next day at school he went up to my best friend and started asking her stuff about me. I didn't even think he knew who my best friend was. He asked her y I moved and if I was going to be coming back. I just think its really weird since I barely talked to him anyways. Why would he go ask her all that? I'm just a little confused.
