Jeffrey Grimes (Comic Series)

"Alright, but I warned you. Rick's brother, Jeff, is my age. I'm two years younger than Rick. I met his brother senior year of high-school."

- Lori to Donna and Carol about Jeff.

Jeffery "Jeff" Grimes is the younger brother of Rick Grimes. He is also the same age as Lori Grimes. Before the apocalypse, he and Lori were good friends, and indirectly caused Rick and Lori to meet. He is not seen after the outbreak, and is most likely dead.

Pre-Apocalypse
Jeff will never have an appearance and has only been mentioned twice, both times by Lori. Much about his past is unknown, aside from that he apparently broke an ankle while in elementary school. This event caused Rick to be beaten up by his peers, for attempting to stick up for Jeff. It was also revealed that he was Lori's best friend in high school, and was indirectly responsible for Lori meeting Rick and "hooking up".

Post-Apocalypse
Nothing is revealed about Jeff's fate. While Lori is talking to Carl, it is hinted at that Jeff may have had a crush on Lori. She states that Jeff rarely came to visit after she and Rick were married.

Jeff's current fate is unknown, and he is presumed deceased.

Rick Grimes
Rick is Jeff's older brother by two years. As a child, Jeffrey acquired a limp for a period because of some accident and Rick frequently fought with those who teased him in order to protect his younger brother. He often lost these fights.

Lori Grimes
Jeff and Lori were friends in high school. Jeff was the one who introduced Lori to Rick at a party. Other than that there is no relationship known about Lori and Jeff.

Carl Grimes
Carl remembers his uncle, but nothing more has been told of him by Rick.
