He returns to the present, only to find that when he killed King Circle, somewhere on the timeline, Teddy wasn't born as a dog, but as William's new neighbor.

Trivia
This is the first time machine shown in the series, with Teddy's creation of another one in Movin' In (Anthony's Song.

This is the second time Mark gave William the wrong object, thus a missionima's plotline started from the mystery wrongly-delivered object. The first time was in Computer Craziness.

It is unknown what happened to Leonard after the death of King Circle.
