Ginnifer Goodwin, Colin O'Donoghue and Lana Parrilla

Before Ariel's highly anticipated arrival next season on Once Upon a Time, other mermaids will make a splash on the ABC hit's Season 3 premiere. But unlike Ariel, these are nasty little fishies. According to Lana Parrilla, her Evil Queen and the rest of the Storybrooke gang traveling to Neverland will encounter a pod of finned creatures who are "beautiful, full-bodied and not the nicest mermaids. They're more like sirens."

Trying to be on her very best behavior, Regina/Evil Queen will find a surprising love connection in the third episode — perhaps with Robin Hood (Sean Maguire), who will appear on both Once and its Wonderland spinoff. "Regina's love has to be very manly, and Robin Hood is that," Parrilla says. "I'm getting very excited." (Alas, she shouldn't get too excited, since producers tell me this romance will take a tragic turn.)

Also expect to learn the origins of Tinker Bell, the Blue Fairy and fairy Nova. And while Rumplestiltskin (Robert Carlyle) and Belle (Emilie de Ravin) are separated in different lands, "Rumbelle" shippers will be treated to what de Ravin calls "a dreamlike reunion/interaction between Mr. Gold and Belle," with the possibility of Belle soon joining her lost love in Neverland. But will they live happily ever after?
