On ONCE UPON A TIME's upcoming episode, titled 'Second Star to the Right,' Emma, Mary Margaret and David go in search of Regina when they discover that she - along with some magic beans - have gone missing. But against Neal's protests, Emma still believes that Tamara had something to do with Regina's disappearance; and Mr. Gold contemplates telling Lacey the truth about his ability to conjure magic. Meanwhile, after Rumplestiltskin abandons his son and lets him travel alone through a portal, young Bae finds himself back in 19th century London and is taken in by the Darling family -- befriending their daughter Wendy -- on SUNDAY, MAY 5 (8:00-9:00 p.m., ET) on ABC.
