iWear's 'Secret' Hideout

There's no obvious signs of an immediate reaction, as indeed why should there be? The villain inside the bunker has no idea it was an infiltration attempt- all she knows is a gas triggered the laser alarm in the fake vents. She thinks someone's trying to break in, and now think she's incapacitated or dead. She's not going to leave to confront her opponent, as she now believes she has the element of surprise- once he makes his way inside.

There is a more subtle reaction, however. In the garden, what looks like a normal burrow has something emerge. A mechanical drone, about the size of rat although slightly longer, with six little wheels is whirring its way to the bungalow where it will try to find the intruder and get a look at them. It's a pretty crude thing, basically a remote control car with a camera mounted to it- and a dodgy camouflage device. It's not invisible, but its colour matches that of its surroundings, with a few seconds lag. It's quite hard to spot in the garden, but once it enters the bungalow itself it'll be easier to see.
