Teacher (a.k.a. Bubble Girl's mom) comes over and asks if there's something going on. Walt tells her that it's just a drill. Teacher laughs, and then says that when people see Walt talking to Johnny, they assume the worst. Teacher laughs nervously, and her cell phone rings. She steps away to answer it. It's her husband, who is stuck outside with a small crowd of people. He asks what's going on, and why they won't let him in, and adds that they've been told that the school is having a lockdown drill. Teacher repeats, "Lockdown?" and Walt overhears. Walt tells Teacher they need to talk privately. Teacher tells her husband she'll find out what's going on, and hangs up. Teacher and Walt walk off. Johnny looks around the gym and sees that many other people's cell phones are ringing. Stupid cell phones! They keep the police from lying to people!

Out in the hall, Walt explains to Teacher that he needs her cooperation. She protests that he can't lock down the school without permission from the principal. Um, he's the sheriff? I think he can do it without a note from his mommy, especially if there is a public health risk. Walt tells Teacher just that -- there's a public health risk.

Speaking of public health risks, the State Health Inspector finally rolls up. The Inspector is played by Stephen Tobolowsky, a quintessential Hey, It's That Guy whom you may remember as Sammy Jankis in Memento. Just to confuse you further, his character's name is Jim Pratt. And Jim Pratt is pissed. He pushes his way through the crowd and flashes his badge at Roscoe, who lets him in.

In the gym, Walt is trying to calm down the parents when Pratt arrives. Walt orders the parents and kids to go back to their booths, and steps outside to fill Pratt in on the situation. Pratt is still pissed, and Walt explains that they may have an outbreak of some virus. Pratt wonders what evidence they have. Johnny walks up and Walt introduces him to Pratt.
