O'Malley was a cruel, murderous, maniac. He disliked most things, which made sense because he was the embodiment of rage. He was the part of Alpha that held his anger and his hatred. There were only a few things he actually liked. Unfortunately, one of those things was an insufferable, idiot by the name of Frank DuFresne.

He would never admit to it to anyone, especially himself, but O'Malley had grown attached to Doc. He had come to care about the pathetic fool. O'Malley hated how endearing he found the lousy medic to be. It was sickening to the AI fragment. It was disturbing how much he adored the Medic's stupid voice or how disgustingly sweet he was. He even liked bickering with Doc, if you could even call it bickering. Boy, it made O'Malley want to kill someone gruesomely.

He hated himself for it, but he truly did care about that pathetic, pacifistic, failure of a medic. The evil, hate filled personification of Rage had come to love his host. His medic. He loved DuFresne

Although he would never tell anyone, O'Malley hated more than anything when Doc was hurt. He hated when someone insulted Doc or made him sad. It was his job to insult Doc. No one else was allowed to call his medic names. DuFresne was his doormat to walk all over and no one elses. Since Doc would not stand up for himself, it became O'Malley's job... which was why he tackled Tucker.

After being trapped in some shit hole dimension with only the memories of his so called Friends trying to save him to keep him going, Doc was crushed to find that no one even noticed he was gone. O'Malley, being a part of DuFresne, could feel how worthless he felt and it pissed him off. So he acted on his rage.

O'Malley threw himself at Tucker and promptly pummeled his sorry ass. Each punch to the face was for Doc. Each insult and threat O'Malley slung was for his host. Each cry of pain Tucker uttered at O'Malley's hands was for his medic. Maybe also for himself too because he enjoyed beating insolent fools senseless, but it was mostly for Doc.

Nobody fucks with DuFresne. Not anymore.
