Answer the following question: Given the following context:  Tim and Susan Gates are eager to move into their new house with their teenage son Shane and their younger son Taylor, as well as their college-bound daughter Kayla, despite the house's dark history of drowned children and foreclosure. As they settle into the house, strange things frequently occur, like the garbage cans being taken out for collection without explanation. While Kayla and her boyfriend Derek are sorting out items for a garage sale, the garage door inexplicably opens and closes.  The next day, the ladder from the crawlspace descends into view, and the house's previous owner Aldon Webber climbs down. He washes up and helps himself to some food, and he retrieves a stuffed unicorn that Kayla had thrown out. Webber's intrusions into the Gates' lives grow more elaborate and sinister as the film progresses. He watches them closely through the air vents, and he even creeps into Kayla's room one night to film her sleeping.  The Gates' elderly neighbor warns Kayla and Shane that they need to get out of the house. She has witnessed Webber moving around when the family is gone during the day. After her warning, Webber sneaks into the neighbor's house and attacks her. He stuffs her vacuum cleaner's hose extension into her mouth and then reverses the air flow, emptying the vacuum's contents down her throat.  Webber's next victim is Taylor's babysitter, who was not watching as the boy played with Shane's paintball gun. At the garage sale, Webber reveals himself to Kayla and Shane, but poses as a customer. When Webber does not leave after the sale is over, Shane approaches him aggressively. Webber punches Shane in the face and walks off the property.  answer the following question:  Who was playing with Shane's painball gun?
Answer:
Taylor
