You're absolutely right, Diego. Jeff Williams said that Red Like Roses Part 2 is about Ruby and Summer. That, and there was a livestream where the RWBY crew were talking about volume 1, and they said that Red Like Roses Part 2 was written specifically because fans were disappointed that the first Red Like Roses barely said anything about Ruby.

So... yeah. RLR2 is about Ruby and Summer, no matter what anyone thinks, no matter how much anyone argues that it's about Yang.
