Originally, the Vatos gang (who appeared in the fourth episode of season 1, “Vatos“) were going to appear in “What Lies Ahead“. Rick and the group were going to go back to the Atlanta Nursing Home after the CDC exploded, only to find out that it has been overrun by walkers. Many of the inhabitants have mysterious gunshot wounds to the end. The group eliminated a few walkers shortly before retaking the guns they gave the gang. They continued on their journey to Fort Benning. Despite the scene was cut, parts of it were used in the Season 2 Trailer. This is no longer considered canon.
