The plane crash mystery

You feel a surge of energy and hit him hard-and I mean HARD. He jumps back in pain, dizzy. As his last try, he sends a powerful bolt of lightning. You start to think this is the end, when suddenly, the villager jumps in and pushes you out of the way. "I figured you needed some help" he said, proudly. The Bargainer falls down, then gives up. Everyone cheers-you and the villager, that is. The Black Bargainer says that one of his robotic helpers has gone out of control, creating a virus. It has already infected your plane, which he is fine with, but he fears it might infect HIS world too. That must have been what he was talking about earlier when he said he'd leave it up to you. The Bargainer falls down dead. What do you do?
