Think back to the first season. When Rick stumbles out of the hospital Morgan and his son Duane are the first live people he runs across. Morgan then reappears in an episode in season 3 called "Clear".
From Wiki:

Rick, Carl, and Michonne travel back to King County, Georgia, to gather weapons to combat The Governor. Along the way, they encounter a backpacker who begs them to stop, but they drive past without stopping. Carl questions Rick as to why he brought Michonne along. Rick says they have common interests. Michonne appreciates Rick trying to connect with her. When they arrive at King County, a masked man attacks the group. Carl shoots the man, who turns out to be Morgan, the man who originally saved Rick. The group brings Morgan, who was wearing a bulletproof vest and was simply rendered unconscious, to his house and raids his gun supply. Carl and Michonne go on a run, seemingly to acquire a crib for Judith. But first, they go to a cafe where a photograph of the Grimes family is on display. Carl and Michonne manage to fight through the walkers inside to retrieve the photograph. Meanwhile, Morgan wakes up and has an altercation with Rick, stabbing him in the shoulder. Rick manages to talk some sense into him, and Morgan explains that his son, Duane, was bitten and infected by his turned wife, whom he had been reluctant to put down. Morgan explains that whenever he turned on his own walkie-talkie every day at dawn, Rick never had his on. Rick invites Morgan to return to the prison with the group, but Morgan refuses, not wanting to witness any more death. Morgan's mission, he believes, is to "clear" the world of walkers. Michonne and Carl return with supplies, and Carl tells Rick: Michonne "may be one of us". Carl apologizes to Morgan for shooting him, to which Morgan responds "don't ever be sorry." As they drive back toward the prison, they pass the backpacker's ravaged remains and his discarded backpack. They stop and take the backpack before moving on.
