"Nate!" Serena exclaimed. So what if he was exactly the person she wanted to avoid. Things were in chaos, this was an emergency and if Nate was outside he could let them in. "Nate!" she banged on the door. "Open up!"
The minute the door opened the smell of marijuana hit her nose and she realized what Nate had been doing up here and that he was stoned. She sighed. Normally she didn't have a problem with it. If somebody wanted to get high that their business and it was standard business among her classmates. But now was not the time to be stoned. Now was the time to be on full alert.
Once she was out on the roof she bent down and put her heels back on. Since they were the best weapon she had, she thought she ought to keep them handy just in case. Even if Carter did have a point that they weren't ideal for climbing out windows.
"Do you have any idea what's going on downstairs?" she demanded of Nate. "There are people eating other people."
Now that the door was opened, the sound of the melee happening downstairs began to drift up to the roof.
