Wasn't Chad saying something about 'them' or 'they' to Sage? sounds like the counselors to me.
The dialog is as follows:
Sage: "You put yourself into this situation. I can't fix that for you."
Chad: "Yes, you can! They will listen to you."
Sage: "... I'm not promising anything."
Interestingly, when Chad is kicked out of the jocks, Stephen says this:
Stephen: "You do understand that you can't expect to keep your position as the president of the tri-alphas after this."
Chad: "What!? C-come on!"
Stephen: "I'm sorry Chad, but I can't think of any scenario where B&R would allow that. You're suspended from any fraternal activities for the near future... ...and consider yourself lucky that we're not going to revoke your scholarship."
It's not clear what "B&R" is referring to here. It could be Stephen referring to some oversight group that he (and Jade and Cathy) must answer to. But it could just be a way of saying he has to represent the college's best interests, even though he (and Jade/Cathy) have final say in the matter.
In the former case, Sage could appeal to that group to overrule Stephen's decision. In the latter case, it sounds like Sage would need to have pull with Stephen, Jade or Cathy directly to make much of a difference.
