When Scar had become a Deleter, a rift had opened up between him, Marcus, and Himmy. The three of them, who used to talk often due to the connection of all being from the same world, had drifted apart.
Marcus, when going to Alter in passing, would try to approach him a few times, but Scar would always state that he was a Deleter, and that the two of them shouldn't chat. Otherwise, who knew what could happen one day? Maybe he would have to get rid of him.
Marcus never took it to heart, but he could tell that ever since Scar had changed into a Deleter, it had affected Himmy. He hadn't talked to him since, nor could he really face him.
Himmy had never told Marcus the reason why, and eventually, it had led to the situation where Himmy, who was on the run trying to aid Raze, had met with Scar once again.
