once upon a time season 3 rose mciver sean maguire 'Once Upon a Time' Season 3 casts Tinkerbell, recasts Robin HoodAt least part of “Once Upon a Time” Season 3 will take place in Neverland, as we saw our intrepid heroes set sail for the “Peter Pan” locale in search of Henry. Now the show has announced who will play one of J.M. Barrie’s classic characters.

Rose McIver has been cast as Tinkerbell, reports EW. The iconic fairy will have a surprising connection to another character and will appear in multiple episodes.

Meanwhile, TV Line reports that Sean Maguire has replaced Tom Ellis as Robin Hood. Ellis was unable to return due to his “Merlin” obligations, so Maguire will step in for a recurring arc.

One big role left to cast? The Little Mermaid, Ariel. Who do you have in mind?

“Once Upon a Time” returns Sunday, Sept. 29 at 8 p.m. ET/PT on ABC.
