Brothers or More?

Mark Fischbach is rich, but lost his mom to some condition she had and they couldn't help her, so without the Fischbach's concent, they pulled the plug. Mark's dad sued the place, and they won. That was unfortenatly over a year and a half ago. About six months after she died, Mr. Fischbach started dating this women by the name of Sea McLoughlin. Mark was okay with it, but it was unexpected that six months later, his dad proposed to her. She said yes, of course, and Mark's dad told him that she had a son by the name of Seán. Mark was gonna hate having another brother- he already hated Tom for everything he did to him. He found out that Mrs. McLoughlin and his son were moving in with them. He was gonna hate this whole situation, but pretend to be happy on the outside.

Jack McLoughlin is not rich, actually very poor after his dad commeted suicide. He came out gay about a week before it happened. Both his parents were supportive of him. His dad reassured him (in the letter) that coming out as gay had nothing to do with him commeting suicide. Jack still doesn't beilive it, and blames himself everyday that this was all his fault. That was almost three years ago. About two years Jack and his mom spending alone time together, she started dating this man by the name of Nick Fischbach. Jack congralated her, and was happy for her. He soon found out that he had to leave Ireland so they could move to LA where Mr. Fischbach lived. Jack had no idea that he was gonna have a step-brother.

Could this be fate for Mark Fischbach and Jack McLoughlin? Or will they destroy each other until they aren't alive anymore?
