William Smee is a supporting character on Once Upon a Time. A known procurer of hard-to-find objects who everyone saw as a measly rat, Smee encountered Rumplestiltskin in a bar where he made a deal that went awry, leading him to be the right-hand man on notorious pirate Captain Hook during their voyage to Neverland. After the Dark Curse hit, he was transported to the town of Storybrooke, Maine with a new identity. However, after the curse was broken, Smee returned to his rat-like ways... in more than one sense.
