Also on top of all this, Philip's already got the love child baby potentially back in Russia, as if every time he has a relationship of any duration the girl's just going to get pregnant.

A baby's just a drag in so many ways, yet it gives Philip a thing he would have to start caring about, splitting his attention from his family etc. I would just hope it's considered dealt with through birth control beforehand so it's a non-issue. But you'd think that would be something they'd discuss before marriage. It seems like Clark's leading Martha to believe there's nothing to discuss, that if she wants kids he'll want kids.
