Both father and son had tons of patience, it is true. I can see the Emperor starting to apologize to his son for losing the throne, messing up the future, and getting them into that mess, and the little Heir doing his best to forget premonitions of the end while assuring his father that the present circumstances were not all his fault.
Interestingly enough: According to something I read on an internet search, Cat Stevens, AKA Yusuf Islam, was supposed to have been working on a musical about the Romanovs and Rasputin at one time and the only thing that was salvaged from the attempt got transformed into the song 'Father and Son'. Wonder if anything in the lyrics still refers to Nicholas and Alexei?
