Well hello there Tifa, I'm Selphie. I am extremely amused at our Final Fantasy names right now.
Anywho. In all seriousness. Gavin is Cedrella's (aka Charlie) baby brothaaaaaaaaaaaa. Which means she's going to poke and prod and be annoying, but loving because that is how she rolls. She is currently bouncing around from Romania and Britain and what not though, so she won't be around every day. :3.
