Whenever Maclin thinks for someone's death, accidentally or intentionally, when the circumstances add up for it to happen, there comes another Maclin out of nowhere to stop him from doing so. -- Maclin loves Natasha from a young age and they both are always close from childhood. She is away from him for a while and comes back after some time. He then knows she is in love with someone else - Michael. That thought itself makes him go out of control and then is when he knows about the other Maclin who comes to stop him from killing, letting Natasha know he wants to kill her and request her to run from him. Being accused as a killer just because of an unknown, and unclear thought and that too from a stranger whom he never saw or knows drives him out of control and gets in conflict with that stranger. In that Conflict, unexpected things happen which completely changes his life forever. And how his life is after that moment is... The thinking Killer.
