Rick had been in a coma for a while after getting shot in his side, so he joined the game of survival a bit late..It was an apocalypse.

He met someone who filled him in, and after a day he set out on his journey, unsure if he'll see any of his family or friends ever again. You, on the other hand, his best friend, his wife and son, assumed he was dead.

When some of your people came back from a supply run saying they had a new member, you didn't think much..until Rick came out of the car.
