The explosion in Tank 3 is so loud that Roger can't hear what's going on, so he stops working on the controls. He's worried that something's wrong with Betty, but she's fine. She's breathing fine, and the surgeon is on his way to check on her. The surgeon says that Betty's pulse is stable, but her blood pressure and heart rate are elevated. He says that he'll talk to the crew about it, but he's got to get Betty to the base first.
