The Alpha in Teen Wolf Revealed?

I think that the alpha is actually Scott's teacher. Not the lacrosse coach teacher the one that they were in detention with because he over heard them talking about stuff and then he let them get out of detention. I think this whole thing with the vet is like supposed to make us think that there is something going on with him being the alpha. maybe he did just get out of the car or maybe he is a werewolf just not the alpha. O_o lol but if he were a wolf just not the alpha that could explain all the mysterious things about him. They are trying to make us think that he is the alpha so that when they reveal the alpha we will be suprised.
