Don't know, could be the sound of walker teeth hitting each other. I could hear sounds of struggling after that. He is more than likely gone though, after him trying to make things better/right with my Lee and ben.
They didn't keep interacting with the gate, Lee keeps calling Kenny.
Why does Christa ask what happened, she's looking down in to the alley, she probably saw more than me. Probably why she gave me a look of pity when I chose to say he could have got away.
