Dr. Gideon, who was seen previously in an episode is able to escape and now seeks revenge on every psychiatrist who treated him. With Dr. Alana Bloom on the list it worsens the condition of Will even further, leading to some unexpected circumstances.
Firstly, the fact that Gideon wanted revenge upon every psychiatrist who treated him, including Bloom (who never referred to him as Chesapeake Ripper), was a bit too far fetched. A man in search for his identity keeps on killing until he finds all the answers, but will Dr. Hannibal help a man who nearly stole his alias? But Hannibal's actions as expected were smart and spot on.
(Spoiler) Secondly, Will who just had a mild seizure and has a temperature of 105 degrees, with undiagnosed Encephalitis and severe hallucinations and headache is able to properly drive as well as kill Dr. Gideon. That seemed a little to fat to be true. Apart from these the episode was well constructed and beautiful in its own way. The technical staff has done a good job.
Acting: Eddie Izzard, Mads were good. Dancy was the stand out performer.
Overall, it could have been better, nevertheless a good one.
