That is a good question!
Does anybody know a really good site where they list all of the Disney Channel shows and the episodes of each one. By the way, does anybody else remember Under the Umbrella Tree?
Well, I don't know if there are any sites or not.
But I think the official last episode of Even Stevens was where it looked like the mother won the Senate election. Louis confessed his true feelings for Tawney, as did Tawney to Louis in video recordings. The father tells off his boss at his lawyer firm and quits. I think the older brother Donnie is ready to go off to college. But it is found out that there was an error in the counting of the votes, and the mother ended up losing, and the father was left without a job. But Louis was pretty happy that they weren't going to move to Washington D.C. after all. I guess they kind of left that episode so they could add more shows if Disney decided to green light another season. I guess the final "hoorah" for Evens Stevens was the Even Stevens Movie made exclusively for the Disney Channel. Pretty much any show that has made a movie has ended the series.
But sorry, I don't know what you are talking about when you refer to Under the Umbrella Tree.
