How was the photographer dragged into the water tank in "Saw 1"? Tell me which part it is.

The answer upstairs is wrong. Let me tell you something. This part is elaborated in the third part. It was Amanda (the old man's female apprentice) who caught Adam and dragged him into the bathtub. Then the old man decorated the bathroom with Amanda. Then a drug was injected to slow down muscle relaxation and breathing, so as to achieve the effect of feigning death. Finally, Adam was strangled by Amanda with plastic sheets. In fact, Adam is poor and naive. Originally he was the winner of the competition, but he was killed by the cruel Amanda.

You can ask me alone if you don't understand.
