Zbigniew is all, "okay, I got it. It was my fault. Your brother was a hero. . you been infected" . The whole gang is freaking out. They can't believe what they've just witnessed. They're all freaking out because they think their brother would have died if they'd all been cooped up together instead of hanging out with the rats. They don't realize that they're actually getting bitten by rats, which is kind of a bummer. The only thing that's keeping them from getting bitten is that their brother is a hero, so they'll have to tell everyone about it. The woman takes the two of them into the store room and shows them a dead rat. It turns out that there's a whole lot of rats in the store, and they need to find a way to get rid of them.
