Ex-CUSE me!? I'm 20, thank you very much!

Oh shit, I'm sorry. lol I don't know who I confused you with, but I thought I remembered you saying that recently, whoops! Enjoy it then!

And Chris,

(Spoiler:) Hoffman (the one in the chair) was the one who built all the traps in this movie, not John. However, his tape at the end stated that even though he was behind the whole thing, he will still be tested. The way I see it, Hoffman may or may not have been more of a copycat that admired his work than a helper, but seeing as someone will have to test him and John is dead, there has to be another person who's the TRUE new Jigsaw, and we don't know who yet. I doubt John was planning to do it before he died, because he always thinks ahead and he knew very well that he'd die.
As for Rigg, the point of his test was to think like Jigsaw (even though Hoffman was behind it), so he can't really be the new Jigsaw... yet, but it was an attempt to recruit him, and we don't know if it was successful or not. We don't even know what they do with him, if they kill him or have him keep quiet.

Even though Hoffman may be working with Jigsaw, he might still be just a pawn like Amanda was, because to him in order to carry on they have to be tested, until then they're just a pawn. Amanda was tested in Saw III and she failed.

I see. I would have likd to see Rigg become the new Jigsaw since I enjoyed seeing his progression and journey through the film, having him gradually learn of the concepts etc. Hoffman was left field and random, and I can't really appreciate his character since he came out of nowhere.
