Why was she still here? School had been over for hours, but Lydia had been insane enough to take AP chemistry and their first lab was due tomorrow. She should have finished the project earlier this week, but there just hadn't been enough time with an art project due, two translations, and some social engagements during the weekend.
So here she was mixing chemicals and finally about to finish up the last of the lap so she could go home, take a bath and then watch a few episodes of the gossip girls.
It was about this time that Lydia actually heard something, or someone outside. It was probably the janitor, but that didn't stop her from carefully pulling out her pepper spray can and stepping towards the door to open it and look outside. Was that Stiles.. and a bunch of other people?
