In the tree-house scene, we're treated to yet another mention of Ron's...experiences in Camp Wannaweep. Considering how terrible his days there were, it says a lot when the worst part, for Ron, was not the evil monkey, the poison Ivy, nor the toxic lake...It was spending the whole Summer without Kim.
When Kim is falling for Eric, and has already seen Ron's jealousy emerging, when she gets word that her father is missing, Ron is the first person she calls on for help.
When Kim is about to give up after discovering that Eric was working for Drakken, resulting in Kim and Ron becoming Drakken's prisoners;
Kim: Drakken won. I should have stuck to babysitting. Ron: Drakken didn't win, KP, he played you. And now it's payback time. And besides, there are guys out there that are better for you than Eric. Guys that are real for one thing. Kim: Do you really think there's a guy out there for me? Ron: Out there... in here...
Perhaps the most heartwarming part of the movie occurred when Kim and Ron shared their First Official Kiss at the end of the film.
Everyone cheering for Kim and Ron when they show up together at the prom.
And this was just after Bonnie tried to use the fact that they were dating to humiliate them... and FAILED!
Rufus pushing Kim and Ron together is also sweet. If it wasn't for him, it might have taken a while for them to work up the courage to dance together.
The song "Could it Be?" that plays during Ron and Kim's dance will give anyone warm fuzzies. It represents what the Kim/Ron ship had been working towards from the beginning, and anyone who's ever found love in an odd situation can totally relate.
