Normally Remus didn't condone violence, but in this case, he too felt strongly about what he'd do if Peter ever showed up in Colligo, "I wouldn't blame you." It was probably the first time he'd ever agreed on something like that and he wouldn't be surprised if Sirius thought he was a pod person or something. "He tricked us all and we paid the price for underestimating him." There were times when Remus still felt awful about thinking that Sirius had been the traitor when it was clear that he would never ever do something like that. How had everything gotten so out of hand back home that they couldn't even trust each other?
