The Wife in the morning (spoiler plot flaw)

I thought that too, but maybe she had no reason to go into that area of the house that morning? She could have just gone from the upstairs straight out the front door, and stopped at a coffee shop on the way to work or whatever. You'd think Hart's character would have said something about it so she wouldn't be surprised if she did walk into the area, but eh.

Don't forget Bob Stone's ninja moves.. He probably made himself invisible to the wife. She didn't stand a chance..

Or how The Rock managed to fix that room up in 20seconds for the CIA people.
