When 5x16 aired I thought having Dorothy return to Oz was the writers way of creating backstory potential for Zelena, giving her the opportunity to have stories with Dorothy that somewhat paralleled Regina's with Snow. In the end we got none of that, and as far as we know Dorothy's just been in Oz all that time. I think 5x16 just opened a lot of doors for Dorothy that were never explored.
