It make sense Rumiko Takahashi said don't think about it. The lore around the jusenkyo is cunfusing and even seems contradicting. Like does Ranma look like the girl who fell into the pool to create the spring of drowned girl, or does he just like a female version of himself. Miss Takahashi just seemed to make choices about lore to fit whatever story plot she was working on at the time.
So, basically on canto 7 we discover that Don Quixote is actually Sancho, a Bloodfiend converted by the original Don Quixote, who was visited by Bari (the girl with blue hair)
In a later story arc, a bad guy nearly drowned Akane to death in fresh jusenkyo spring so he could turn himself into an Akane look alike to mess with Ranma.
