He didn't want William, but refused to lose him. He wanted William to be by his side, but he didn't want to be by William's side. He wanted William's love, but he didn't want to love William back.

Sinister Mark knew it wasn't fair to William...he was dating William but was detached he didn't show any affection to boy who gave him unconditional love, he was possessive with the boy while he would flirt with other guys and girls infront of William just because he could, he hated it when William left to go literally anywhere without telling him.

he hated it when others came near William, the thought of William leaving him made his blood boil he hated the thought and would kill anyone to make sure the thought didn't come true.

William left him. him. For some nobody named Rick Sheridan....that bastard stole what was his and he would pay with his life.

Sinister Mark had killed his version of Rick Sheridan and William but now here he was in another world and when he saw Rick Sheridan in this world he killed and ate his dead corpses flesh he didn't care what he had to do if it meant he kept what was always his.

once he was done Sinister Mark had left the corpse and flew to William's house watching as this worlds William anxiously calls Ricks phone over and over and over again, William knew full well of multiple Mark variants that were flying around and of what they could do and from what he knew it was quite obvious one of the Mark's had done something to Rick and he was just praying that it wasn't true and that his boyfriend was still alive when Sinister Mark walked into Williams room from his window in his yellow and black invincible hero suit with blood all over him mostly on his mouth with Ricks ringing phone in hand "he's not gonna answer darling..." Sinister Mark said with a sadistic and Sinister smile the blood evident on his teeth that were stained yellow from how much blood has been on them from the countless lives he's taken
