I still find the teacher in Erased to be very suspicious. Most of that suspicion faded when he was helping Satoru with Kayo but as soon as the issue was resolved not only did all of the suspicion I had before return but it also nearly doubled. It doesn’t help that it was discovered that the teacher has a compartment in his car which he keeps filled with candy. Also when this was discovered he acted as though there was a more serious reason than simply using all that candy to help him cope with the smoking addiction he broke years before. His story just doesn’t add up. I am sure that the truth about his character will come to light as the series progresses and rushes towards its end.
