When Tom heard the panicking scream, he had the same idea as Vincent to leave. He placed his Shotgun onto his back, and taking out his K-Bar when he was in the marines. He remembered the last guys comment about gunfire attracting the zombies, he was probably right. He ran out the back door. He was outside watching for any walkers. Tom said to everyone still inside "You heard what he said. All of you get a move on." Tom was making the suggestion they all should come together, it would be safer in numbers.
