The Black Pearl - S1.E17

When a stranger visits and claims to have been a friend of John Ramsey, Alec's father, no one is suspicious. They should be though, because Smythe was no friend of John's. Smythe in an attempt to recover some rare black pearls that he believes John sent home to Belle and Alec, kidnaps Alec and the Black. It's up to Henry, and the pearls, to get them back.
