A Case of Alien Hand Turns Out to Be 'Watson's' Twistiest Adventure Yet

The title of this week's Watson is "The Man with the Alien Hand." That immediately brings up images of James Moriarty (Randall Park) and his fused fingers, but he wasn't the eponymous character in this case. That honor belonged to a wealthy man named Cameron Phipps (David Thompson) who underwent surgery to separate the two lobes of his brain to cure his severe epilepsy. The significant side effect was that it left his left hand to act on its own volition, and apparently, Cameron's hand really wanted to kill him. Well, actually, it turned out to be more deadly for the people around Cameron than himself, as this became one of the clinic's twistiest cases yet.

As the team worked on the case, Ingrid (Eve Harlow) was eager to prove that she could still be helpful to John (Morris Chestnut) in hopes that he would talk to Mary (Rochelle Aytes) about letting Ingrid keep her job. The neurologist could accept giving up her place on the spinal study, but she did not want to lose her spot at the Holmes Clinic. It was going to take a lot more than heartfelt apologies for him to win over the hospital boss after the ethical lines that Ingrid crossed.

She wasn't the only one crossing lines, either. Shinwell (Ritchie Coster) got a new assignment from Team Moriarty at the top of the episode: collect DNA samples from all of the fellows. Moriarty already had Shinwell's DNA, but he was looking to do something dastardly with the rest of the team.
