Bailey -- who will be back for at least one episode -- is set to make his fairytale return in the first half of season six.
The last time viewers saw our favorite puppet-turned-real-boy (Hmm… or should we say attractive man?), it was on Once's season four finale, "Operation Mongoose Part 1," when he helped direct the heroes to find the Apprentice and potentially stop Isaac, the author at the time.
And if we're getting really technical here, the last time August was mentioned was in the season five finale, "An Untold Story," when our heroes were searching for a way to restore magic. The Dragon encouraged Emma to use what August taught her: that one has to believe in magic in order for it to be seen.
Once Upon a Time airs Sundays at 8 p.m. ET/PT on ABC.
