As we all know, Inception was riddled with mystery and sure fire multiple viewing purposes. If you haven’t seen Inception yet, stop reading now because MAJOR SPOILERS are ahead. The entire movie will be spoiled for you so I suggest if you don’t want to read further, that you don’t.
MAJOR SPOILERS AHEAD
I think the whole thing with Cobb planting the idea in Mal, never happened the way he says it did. I think Mal PERFECTLY knew that that they had gotten out of limbo and were in reality. She and Cobb had shared limbo together for 50 years in the dream world. I don’t think she wanted to let that go. there are subtle hints through the movie where it shows Mal all depressed. She wanted back into a place that she and Cobb could spend forever together. When she knew she couldn’t have it, she thought that if she kills herself, Cobb will do it with her and they can spend death together.
That’s just my theory. So I think Cobb’s got it all wrong, I don’t think the idea grew in her like he said.
The end- I don’t think it’s a dream at the end. Cobb wakes up on the plane and to prove it’s reality, just before then Saito grabs for the gun, implying he killed Cobb and himself to get them out of limbo.
Just my theories, what do you guys think?
