Haven't read much with them but he seems kinda older. Maybe it is the nature of his mutation that makes him look older.

Yeah, I have heard about the whole thing with Idie's age. That she was originally 12 but she seemed a lot older and they made her 14. So no age has been stated for Teon?

He seems older, but i agree that it's the mutation's doing.  
 
I really do hope that he starts talking more, he said more this issue :D.

 the alpha is the individual in the community with the highest rank. Where one male and one female fulfill this role, they are referred to as the alpha pair (the term varies when several females fulfill this role – it is extremely rare among mammals for several males to fulfill this role with one female). Other animals in the same social group may exhibit deference or other symbolic signs of respect particular to their species towards the alpha.

@superboyrocks13: Because Wolverine is kinda the top dog of Marvel's feral characters. Hence the term Alpha or Alpha male

Since his parents faught for custody of him, is it safe to say that he is under 18?
