Which Former Vampire Diaries Star Landed a Guest Spot on Castle?

Kelly Hu (Pearl) is playing a bodyguard named Scarlett on the upcoming Castle episode. We can’t wait! She was also kickass in a recent episode of Arrow, another CW show we’re digging. While we’d love to see her on TVD again, it would have to be in flashback, since she and Anna (Malese Jow) seemed to have resolved their ephemeral issues in Season 3, Episode 7, “Ghost World.”
