Huh. I thought I watched it. But clearly I fell asleep, what with it being two o'clock in the morning and all. Which is too bad, because the next day, thinking I'd watched it, I deleted it.

Care to explicate?

I just watched Mad Men now. Draper's mother was a prostitute who died in childbirth. After she died he was brought to his father and his father's wife. After his father died he was raised by his stepmother and her new husband.

I'm going to rewatch On Demand - I didn't get the reveal either because I was sleepy.

Anyway, I think it says alot about how he feels about Rachel that she is the one that he revealed that information to.

It really wasn't much that we already didn't know. I'm more surprised to see Don admitting it, rather than seeing it in flashback.

Okay.

It's interesting to think what societal pressures must have been in place in the era for the wife to stay with the husband, even with a physical sign of his infidelity.

Although, it does seem like it would have been difficult to prove who fathered a prostitute's child at that time. No DNA tests. Seems like young Dick would have just ended up in a foundlings home.

During the depression? It was probably a question of economic survival.

Ultimate Force: Is that the Annie actress from Life on Mars playing Jamie's sister? (Not Jamie Bamber - -the character named Jamie.)

I haven't seen UF, but a bit of IMDBing says Yes! It's Liz White [link]

She was also a "good christian woman". She wouldn't have wanted the child to suffer for her husband's perfidity.
