John Kramer: I still have a lot of work that needs to be done.
John Kramer: Hello, everyone. It's time to play a game. You all pretended to cure me. But what I have planned for each of you, is very real.
Mark Hoffman: Out of all the men to cheat, you pick John Kramer?
Visible crew/equipment: When John returns to the clinic to drop off a gift for Gabriele, when the cab pulls up, for a split second, you can see what appears to be the reflection of a crew member (likely part of the camera crew) walking in the green doors right before John opens his door. (It's very hard to see, but you can see it if you pay close attention.)
Question: Cecilia states that she realised that John Kramer was Jigsaw, and she got worried. How did she figure out who he was, and since she found out, why did she still insist on scamming him?
Answer: If I recall correctly, nothing in the movie or her dialogue indicates she knew he was Jigsaw before he captured her. To me, it came across that her dialogue was referring to her realizing the truth when she was captured and placed into her test.
