As the movie started to near the end Nick and Judy were feeling a tugging sensation in their bodies if anyone looked at them they would have started to see their body start to turn into pixels and were getting pulled into the screen it started at the feet and slowly started to make its way up their bodies.
Soon it was at their stomachs still pulling more pixels into the screen, it then reached their necks Nick looked over at Judy and just before they disappeared said “That was a good Film wasn’t it Carrots?”
“It sure was Nick”
And with that they disappeared from the world completely.
No one would even remember John and Katie ever existing not even themselves.
