what happened to adam in saw 1

Adam is left trapped in the bathroom at the end of Saw (2004), when John Kramer reveals himself as Jigsaw, turns off the lights, shuts the door, and leaves him behind to die.

What happened to him

• Adam spends most of the movie chained in the bathroom with Dr. Gordon.

• When the twist is revealed, the key to Adam’s chain is shown to have been lost down the drain earlier.

• In the original film’s ending, Jigsaw leaves Adam alone in the room and says “Game Over.”

Later fate

Adam is later confirmed in franchise material to have been killed after the first film, with Amanda suffocating him out of pity.
