He never did tho. Probably would have followed Yunder even if he told him not to. He's a real pain. Bitch-chan
Plus if he didn't took him with them & he would just follow, it would have been harder for that guy to get close. It was his plan to get near them as much as possible. That's why he tried to convince him to take him with them
You shouldn't have trusted that guy..(〜 ̄△ ̄)〜
