In a scenario like this, the Alphas which took part in assaulting the Dik mansion, should all be expelled and eventually face charges, problem solved permanently (and in a CHICK way).
Also no risks for the Dik's if they are attacked in their own home, with a teacher and Jill as witness and Rusty as victim. Why even bother with nonsense like making up with them at this point, making up can be happen with the ones which had the brains and refused to take part in such a stupid action, well if their frat isn't closed down, but again who cares ¯\_(ツ)_/¯
