Question for anybody who has seen "SAW"

[kaz35]

just been to see the film "SAW."  Thought it wasn't bad (apart from the chained up doctor's hammy acting) right up until the last 10 minutes or so.....CAN ANYBODY PLEASE EXPLAIN THE TWIST AT THE END???  I thought that the porter fella was in on the murders with the patient / murderer, my other half thought that the porter himself was a victim given his own killing task - if that's the case, how did he know where the 2 prisoners were being chained up in the chase scene toward the end??  Am i being dull or did I miss something....

The porter was given the task of killing them, just the way everyone else had been given tasks to keep themselves alive. The murderer had told him where they were on the tape he had left for him. The twist was we were supposed to think that when they had killed the porter everything would be fine and they were safe, but it turns out the porter was just another victim and they had been in the room with the murderer all along (the person playing dead on the floor)
