Finch and his brothers enter the staffroom, where Parsons stands fussily: "What is it now, Mr. Finch?" I like that he's a minor character with an understandable issue: he's the only teacher left in the whole department, so he's more iffy about everything than he would be if it were weighted some other way, departmentally, which of course works off the fact that they're using computers and all that to get their...oh, they just ate him.
The Doctor clenches his screwdriver between his teeth and rips out wires and hangs them around his neck and sonics the computer guts and is very awesome. Sarah Jane watches, anxious, but the Doctor can't figure out the way in. "There's gotta be something inside here," he grits. "What're they teaching those kids?"
Wagner holds a door open for the children bundling into the classroom; Kenny is left outside, having lagged behind. He steps back, still weirded out, and looks up at the building.
Finch enters his office and sits, tapping keys on the keyboard to close the school. He belches up some head of the Math department that's repeating on him, and then every door in the school slams shut.
Wagner brings up the Matrix code on the computer screens; the children's heads snap to and they begin to type.
"You wanted the program: there it is," breathes Sarah Jane, looking at the code streaming across every screen.
Kenny runs around the school, staring into windows, getting more and more terrified, and comes up against the front doors. Mickey notices him rattling the door, and gets out of the car.
The Doctor puts something together, and his jaw drops. "No, they can't be..."
Kenny shouts to Mickey, "They've taken them all!" All the children. Mickey runs back to the car and presses random K-9 buttons, frantically. If this show only had a laugh track. Finally, after a whack on the head, K-9 wakes up. Mickey: "No time to explain, we need to get inside the school. Do you have like, I dunno, a lock-picking device?" K-9 dumbly says, "We are in a car." Maybe a drill attachment? "We are in a car." Mickey gets annoyed: "Fat lot of good, you are." K-9's clever: "We are in a car." Mickey finally gets it and shouts to Kenny, in the glass doorway, "Get back!" This is going to rule.
