Daniel appeared in Saw II as the son of Detective Eric Matthews. During a visitation with his father, Daniel gets caught shoplifting which sparks an argument with his father. After suggesting he go back to his mother's early, Daniel was told to just leave and went missing. As Eric Matthews uncovered Jigsaw's lair, he discovered that his son had been taken prisoner in the Nerve Gas House along with seven others. The seven others were all arrested at one point or another by Eric, but only after having evidence planted against them by the detective. He assisted Laura in getting from room to room, and spoke with Amanda about how to survive as well as helping her from the needle pit. After heading off with the three women, Daniel realized that his dad set up the others in the house. Laura died, and Addison and Amanda turned their backs on Daniel, knowing he was the corrupt detective's son, despite his protests that he didn't know. At that point, Xavier started his rampage through the house looking for the numbers on the back of everyone's neck (Daniel's number was never revealed, however). Amanda, seeing that Jonas has been murdered, turned back and grabbed Daniel to help him. She led him into the foundation of the house, while Xavier followed close behind. As Daniel weakened, Amanda helped him to keep moving, eventually ending up in the bathroom trap from the first movie. Daniel appeared to pass out on the floor, leading Amanda to believe he had succumbed to the nerve gas. However, he sprung to life when Xavier reached for him, killing him by slicing his neck with a leftover hacksaw, in the process saving himself and Amanda. After surviving for so long in the Nerve Gas House, he was administered an antidote by Amanda. She brought him to Jigsaw's lair to be locked in a safe with oxygen, as part of Eric's test. The safe later opened up, revealing to Kerry and the rest of the SWAT team that he was alive Show less «
