I didn't see that one.
And in my opinion if he didn't get out he will.
The top either fell or kept spinning. Eventually he would have had to go back in that kitchen, and if it was still spinning he would have shot himself in the head right there (possibly, or just chosen to forget it and live with dream kids or whatever). If it wasn't, then yay.
I guess that kinda takes the magic out of the ending but eh.
