Something about Tooru is super suspicious. He stops Yasuho while Josuke and Rai are chasing Satoru, trying to separate her from the group because he's jealous. He wants to keep Yasuho, but kill Josuke and Rai. Then, he gets questioned and the Head Doctor is there all of a sudden. Also hes not even wearing his white coat like all the workers are.. the Head Doctor isn't a rock human, he wouldn't look old at age 89 if that was the case. He's a stand illusion.
