Caution: spoilers.
This first aired in 2003, in the middle of season two of Kim Possible. (The title is a reference to one of Kim's catchphrases, "What's the sitch?") It's available on the season 2 DVD set as well as an individual DVD of the movie, and was broken up into three episodes on Disney+. I watched it on the DVD of the movie in 2024 (hard to believe it's been a little over 20 years since I saw it last). It's possible I loved it a little bit less this time than I did when it first aired, but I still loved it.
So, Ron finds out he's moving to Norway because his mom got a new job there. He and Kim are really upset to be separated, but they stay in touch via communicator, and Ron keeps trying to get back for Kim's missions, though he usually arrives too late. Meanwhile, Dr. Drakken, Shego, Monkey Fist, and Duff Killigan team up to steal a small, headless monkey statue called the Tempus Simia. Then they have to search for the statuette's head. Kim recruits Monique to take Ron's place while she tries to stop the villains, but the bad guys succeed in uniting the two parts of the statue, which allows them to travel in time. Kim is subsequently visited by a descendant of Rufus, named Rufus 3000 (voiced by Michael Dorn), who gives her a time travel bracelet so she can thwart the villains' plans, because 20 years in the future, the world has been taken over by "the Supreme One". Ron does finally join Kim, and they travel to various points in time together, before eventually traveling to the future, where they are helped by some unexpected allies.
That's basically all I want to say about the plot, except that of course the good guys win in the end, and the timeline is restored to what it was meant to be, with Kim and Ron having no memory of the adventure. The movie was mostly pretty funny, with some cool concepts, and a nice twist concerning the Supreme One. (I don't remember whether I predicted it the first time I watched the movie, but I feel like I probably did. It was still cool.) Anyway, the whole movie was fun, and kind of nostalgic to me (though feeling nostalgia for the early 2000s makes me feel pretty old; I'm used to being nostalgic about the 80s and 90s).
