Fusion Mysteries

I have a câu hỏi about Bismuth and Pearl. Do bạn remember how Pearl jumped into Bismuth's arms? Well if they were happy to see each other shouldn't they have fused? The only thing that could not have made this fusion possible was if Bismuth was not happy. Maybe Bismuth was not happy because of what happened between her and Rose Quartz. (If bạn watched to the end of the episode where Bismuth came in bạn would understand.) I still have 2 thêm questions. Why didn't Bismuth tell the Crystal Gems about what happened? Also, what did Rose Quartz tell the Crystal Gems about Bismuth's disappearance. Anyway I hope these made bạn think a little.
