Season 6 will have multiple shorter arcs like this. The LoUS will be the underlying foundation for all of hte stories this year. J&H was the first mini-arc spanning from last season's finale to "Strange Case", Aladdin and Jasmine will cover the next few episodes, probably concluding with "Wish you were here". And we know we are getting Robin for multiple episodes, and I imagine that that will be one of the first arcs after the winter break.

Eion Bailey will be back in the fall (sometime between 6x06 and 6x10), and I would put the chances pretty high that his appearance and the appearace of the Dragon are connected somehow. It sounds like Eion hasn't actually started filming yet, which implies he will be back at 610, at the earliest.
