The one where Gus have a list of acceptable behavior that apply in the "no fun house" in Canada. The list have things like "don't ask to talk to you father when he's on the phone to mommy", "don't talk about wanting to move home" and so on.
Brian finds the list and he is not happy about it.
I also think that he's in a relationship with Justin but no one knows (or it could be a separate story) - Gus meets Justin at Brian's and it's love at first sight. He keeps talking about his "Jus" (or something like that) and even manages to call Justin on the phone - whilst talking to Gus, Justin overhears how Melanie hits Gus because he was playing with the phone. She doesn't realize that he's actually talking to someone real.
There's also a friend of Brian and Justin who dates someone in "the gang" and at a dinner at Deb's he immediately recognizes Gus' bruises as abuse and calls Brian to come get Gus.
Am I remembering one story or two? Anyone?
