I was rewatching Season 1 Episode 4, Vatos, and I looked closer at the scene where Glenn is brought to the roof of the Vatos hideout overlooking Rick and Daryl when they have Miguel. One of the men holding him looks like Travis Love, aka Shumpert, and I thought is it possible Shumpert was a member of the Vatos gang before joining Woodbury
