Peter, now that wolf will probably have a lot of information, it is just getting him to talk that’s the hard part. His uncle-in-law for all practical purposes doesn’t like him, might have something to do with the fact he bound Peter to Derek, so that never could the wolf cause harm to the pack or his nephew, never could he harm them for self gain, and several other interesting tidbits that he’s sure some would classify as morally gray. So, good source of information.
