When Stitch spots a croupier at the blackjack table running a 'top-hatting' scam with a shifty looking man he drags her outside and orders her to end the scam.

Stitch spots Nathan close by and demands his help. Nathan is impressed with Stitches handiwork and learns that he's a consultant. At the hospital, tension mounts when Stitch tries to take over as Selena tends to the croupier. He pressures Selena and Guppy to treat what he thinks is a tracheal bronchial injury but Selena thinks it's something else. And when the power fails Selena is unable to prove that she's right. That night, Stitch tells Selena he's looking forward to working with her - as he leaves the hospital with a sexy nurse... Guest Stars: Peter O'Brien, Tom Hopper,
