A lot has been already said about this episode being The Best of Season 3 and I simply have to agree. It's hard to highlight a performance in a series which the greatest highlight is the acting and I didn't expect to be so moved by any other depiction after the wonderful John Lithgow left the series with Churchill's death. But I was wrong and my mistake is represented by two words: JOSH O'CONNOR!!! Eager to see how he develops his character. Astonishing!
