remember Cobb said Mal thought their kids were projections, right? And she thought they had real kids aside from them.

But then at the end Mal said something about loving the kids and she referred to them as James and Phillipa(sp?).

And i think at the end, James and Phillipa were the names of the 2 kids.

Cobb could never give Mal up, and he finally relented to the "idea" he formed in Mal's head. It happens all the time. You want somebody so bad or can't let them go, your world becomes their world, no matter how crazy it is.

but then again this could be another Shutter Island. all this sh*t was in his head to begin with, he is just one crazy muthaf*cker.

where was Chuck when you need him, right? lol
