This is where I think the laptop could come in to play. Perhaps they'll confiscate it and put a ban on the DIKs social media, and maybe even suspend all frat activities, such as parties, for a period of time. They might also issue them with a fine to be paid to the school and have them make a formal, public apology to Cathy. The school would probably also announce some kind of "formal inquiry" in order to show that they're taking it seriously.
It'll be Cathy, Jade, and Stephen again, just like it was with the Chad incident, since there's apparently only 4 people who teach at B&R and they're 3 of them.
