Oh my god THANK YOU FOR SAYING IT!!! Seriously I was thinking this ever since the end of Vol 3, but I was too afraid to say anything because, you know, mourning and all. But seriously, I really do think that RoseArc might have a chance now, if at least a small one, it would make for great character development and I have a feeling that they might draw some parallels to what Taiyang and Summer's relationship may have been like, which I feel like may have been a sort of "rebound" situation from Raven disappearing, just a thought.
