Dancing with the stars?

Why did you guys vote Jennie and Derek off! They were my favorite couple and they didn't deserve to go next. Marie and Jonathan should have gone, they are good but someone has to go and they're the worst out of the four contestants. Mel and Helio should stay too, but why was Jennie voted. Next time actually vote for the best people, not people you feel bad for. Who do you think should win? Mel, Helio or Marie?
