Xavier returns to the safe room, trying
in vain to open the safe until he notices a number tattooed on the
back of Gus' head. Jigsaw's clue from the first tape plays in his
mind, as the proverbial light bulb goes off over his thick skull. He
kills Jonas and gets the number off his neck, taking off after the
rest of the survivors.
They're across the house, Laura finally
finding the X Jigsaw mentioned way back when on a picture frame.
Addison looks behind it to find a picture of Matthews and Daniel,
confronting him over this but Laura has the courtesy to break up the
tension by dying. Now THAT'S how you change an awkward subject!
Addison decides she can't trust anyone and takes off on her own.
Xavier gets the number off Obi's remains while Amanda discovers
Jonas' body and drags Daniel to safety.
I can't help but wonder what the point
of this little plot was, as Jigsaw said when they found 'X' it'd help
them all realize why they're there. Sure, Matthews arrested all of
them but how it THAT going to help? All it's going to do is make
them turn on Daniel and probably try to kill him, which is VIOLENTLY
counterproductive to Jigsaw's master plan. I guess since Jigsaw can
anticipate everyone's decisions in perfect detail he knew by the time
it was discovered most of them would be dead and it wouldn't matter,
but still it seems like an odd thing to leave hanging out there.
