I don't know if people noticed but there's an implication in the press, Ruby ends up in the underworld because her quest to find Dorothy brings her there, it means one of them goes to the Underworld using the slippers and the other one is likely there because... she is dead. Also, the fact that Ruby leaves Mulan to find the missing Dorothy makes me question who's the couple here.

If Ruby is still alive at the end of the episode I hope she returns for the finale, I still doubt it because she wasn't on set but, who knows.
