Mark
Mark was at his desk in his room, notebook in front of him and pen in his hand. To the untrained eye, the appearence of the nearby textbook would make people assue he was merely doing homework.
He was doing 'homework' all right. Homework on the other students.
Mark had secreted probes around the mansion. They were stuck to walls and commoflaged to blend in with the colour scheme. All he had to do was sit back, listen and watch what those rooms had to say. Brought new meaning to the words "the walls have ears".
The downside was, however, that he could only really focus on one probe at a time, and at best have only vague sensations of what was happening with other probes. One day...
At any rate, this fine day he was watching Bobby's old friend, Nicole. Man, she was a babe. A very naughty babe though. She should not be allowed to get away with half the stuff - oh wait... she wouldn't. He would make certain of that.
Mark jotted down some more notes. Just wait until Scott heard about this. Smoking on school premesis! Shame on her.
