Michael notes the situation has quickly become a "shooting gallery." They manage to eliminate a wave of attackers, but Victor questions whether they should go after Saul. Michael, coughing from gas seeping out of the tunnel, realizes he can't even get close to the entrance. They debate leaving him, but ultimately decide they can't stay either. Saul weakly calls out from inside, and they hear more zombies approaching. Victor gets in the truck to get in the cab, plowing through zombies as he does. They slide and hit even more zombies as Michael makes another round to find Saul, Victor is worried they are being followed and swerving. They thought they heard Saul and want to make another go at him. Michael asks victor to man the turret.

After learning that Saul was scratched, Tanya says that Datu was also scratched when he was bitten. She also notes that The group has been marked by an outside group of people.
