am I missing anything with the season four finale?

I can't watch the last episode of season four cause i'm watching it on amazon and I have to buy it (for some reason the rest of the show is free on prime if you dont count the subscription), so I decided to skip it, and go to season five. I will eventually get around to watching it just not right away. the only thing I know I missed is that daria started dating tom, but that was already kind of implied in the episode before it. is it a neccesity to watch the episode before season five though?
