Amsterdam: "Immortality? What's that?"
I wasn't sure about the part early in the episode where Sarah discovered a gray-hair on John's head. Was that a dream? He woke-up pretty quickly after that. And to the sight of his dog, too. How disappointing for him.
Regarding John's sobrity, I liked young-Omar's lack of coherent reaction to his father telling him the truth about his nearly 400 years of life. It looked very overwhelmed and definately needed a few moments to think.
We heard a lot of tiny tid-bits about John's past: chasing down John Wilkes Booth, his relationship with Emily Dickenson (it should be a contest to see how many poets that mention in the length of the series; so far I count 3!), even the fact that he has fathered 63 children!! You can't blame Sarah for not believing him.
The question I have for next week is whether the kid mentioned in next week's show is one he has accounted for or not?
