The plan was simple: Barry would operate the winch platform that brings the soldiers down to escape from the fortress and they will wait for that rescue boat to arrives, while you stood close by, ready to shoot any of the undeads that came near him. The plan went off without a hitch.

Now it was time for the next step. Barry would raise the platform again to allow you to escape, which meant he would be the one to stay behind and sacrifice himself. You weren't aware of this plan, so it's understandable if you going to yelled at him for it. That thought made Barry chuckle weakly.

As Barry successfully raised the platform, he turned to you. "Give me your sabre and get on it. I'll lower the platform while tried to kill any zombies that come near, hurry!"
