"We're three of the smartest people in this school." Lydia says determinedly. "We're only stuck if we want to be, and if we've all gotten this message, than everyone else has too. Which means quite a few people are going to be trying to get to the central computer room."

She looks at both Stiles and Gwen, a thoughtful expression on her face. "This might be a real emergency. Or it might be a test. It may not matter. We should try and figure out a way to help others get to the central computer if we can't make it ourselves. Can either of you text or call other people or is the wifi and cell reception completely compromised?"
