6. Daryl Chooses His Brother Over His Buddies (Episode 9, 'The Suicide King')
After the prison gang stages a dramatic rescue and frees Daryl and Merle from the Governor's death match, Rick puts his foot down: Merle will not be allowed into the prison, no way, no how. After all, he beat Glenn to a bloody pulp and led Maggie straight to the Governor's rape lair. But Daryl abandoned his brother once, way back in season one, when they left him handcuffed to a roof in the middle of a zombie invasion. And he's not going to do it again. If Merle isn't welcome at the prison, then Daryl will give up his newfound family of friends and will seek his destiny alone with his racist brother. Bad news bears, Daryl. This is never going to work out. You've matured so much! You've evolved! And Merle is still a racist jerk!
