Oh My Gosh!!!! I loved this episode!! I think it's the best one yet! Okay... when Phil and keel are voted cutest couple for the yearbook, they decide they want to hook up. (finally!) They're having a good time being a couple (giving the classic salt and pepper shakers to each other) but as Phil arrives home to give his family the good news, he discovers that Pim fixed the time machine and they're heading home. The next day he tells Keely that the time machine got fixed and that he was heading home the following morning. Keely's hurt and doen't come to say good-bye to Phil, but changed her mind right as the Diffy's took off. Phil then discovers that he can't go back to 2121 until he tells Keely how he feels. They head back and he bursts into the broadcast lab and kisses Keely! Phil tells Keely how he feels and kisses her again. Then, sadly, Phil has to go back to his time. I loved this episode, but I'm really upset that this was the last one. I think they should've made a new season with Phil returning to the future, but that's not going to happen. :(
