can someone please tell me why none of the other alphas on the show can turn into the big monster thing like peter from season 1? doesn't that make them stronger? I know alphas can do it because Dereks sister looked like that too when she turned alpha. or maybe the effect was too costly to the show and they scraped the alphas transformation idea altogether?
