Usually when you tunnel someone you go at it with a force and there seems to be a sense to get people to follow you on the lynch. With XIII it's felt more you the two of you bickering at each other. XIII is being bullheaded and acting out on some vendetta and you got annoyed with it and are countering him on it as being his way of avoiding actual contribution.
People will follow me. Don't presume to call me a liar or you're going to see that side of me you keep bringing up, and that's a promise. It has nothing to do with me being annoyed with him, and every reason to do with him being scum.
