Here we get to learn about Philip, such an integral person of the monarchy since 1947. I enjoyed viewing this episode; I liked the character portrayal of the Duke, they, the writers, really touched all the bases -- 'boys will be boys', his love of being at sea, interviewing correctly as a true royal, experiencing moments of sadness in memory, doing the right thing by the lost sailor, his lovely Christmas speech and finally, his homesickness. Just wonderful!
