I don't think you're here anymore, but I believe they got together after the second TV movie, Kim Possible: So the Drama. Either that, or when the last series started.
I want to bed at 2:30am, couldn't get to sleep, a hole appeared in this new pillow I have and the stuffing was coming out. I turned the light on so I could put it somewhere else, and it was 4:00am. Then I finally got to sleep and woke up at 2:00pm.
