He knows the shortcuts and (hilariously) will not hesitate to smash through his own window to catch up and grab you. If the neighbor suspects you're trespassing, the hunt is on and there's little chance you'll be able to evade him, especially early on in the game. Lurk in the ground floor hall too frequently and he'll begin to place hidden cameras. Make a habit out of entering through the backyard window and he'll begin to set traps there. As you make your way further through the deceptively complex home, the neighbor learns from your mistakes.
While the neighbor may not evoke terror in appearance, the AI is not to be underestimated.
