Did Kevin Flynn and Sam Flynn have a relationship with Quorra?

I believe he did. When you re-watch the movie and play back some scenes you notice that Quorra and Kevin have a secret. Kind of like how when you had a fling with your bestfriends wife and he doesn't know it but you and his wife know.

I also believe that Quorra and Sam also did it as well. Thats why Kevin was upset at Sam for a moment. But he let it go because he knows that humans are weak and need to feel love and be loved.

When you pause a frame you can see a book about sex. I believe Quorra is The Grids Mistress. She's the fist live program to be sexual. She is probably now pregnant with either Kevin or Sam's kid because they didn't wear condoms or the programs anti-virus is the condom.
