Wicked Wizard of the West wrote: Wow, so here's another guess: they'll make the finale a Robin-centric, that's why the two brothers will appear in both episodes - for the flashback sequences. OUaT did that in before in Season 2, when they introduced Neverland. So, it would not be so far-fetched to use have the Season 5 finale be a Robin Hood-centric, while helping introduce the storyline for Season 6.... an Arabian Nights arc.

Theory time:

Ali Baba and Cassim encounter the Forty Thieves, led by the Prince of Thieves himself, Robin of Locksey. Remenber, Robin was not yet known as Robin Hood. Cassim has a teenage son named Aladdin, who is in love with the Crown Princess of Agrabah, Jasmine. Princess Jasmine has an evil half-brother named Jafar, who was turned into a genie.... everyone is related!!!!
