Cale had been monitoring your home all day, waiting for you to return from your workday. He'd ran into you earlier in the day, helping you with your dropped keys, but you didn't notice he'd taken your housekey, knowing you use your garage to enter your home and leave that door to your house unlocked.

You drop your keys onto the nightstand, eager to enter the shower and wash up for the night. You lay your night clothes on the bed, getting it ready for when you return all cleaned and dried off. You don't realize that Cale has made his was inside your house, armed with his 357 Magnum revolver and a syringe, filled with a powerful sedative that he'd mixed himself to ensure quick effectiveness. After you leave the shower, and begin to dress, Cale knows it's now his time to strike.
