wait... isn't topanga pregnant with a boy at the end of the series?
No, Topanga was never pregnant in the show. There was an episode where everyone confused her weight gain for her being pregnant, but that was it. It was pretty obvious that they wanted kids at one point, but they never went through with it during the show.
Cory's mom did have another boy, so you may be thinking of that.
at the end of the series Shaun, topanga, corey and eric went to nyc ( topanga got a job offer there).
Yes, but you said that you guess that means they won't be in NYC anymore. What does that have to do with anything? Just because they have a kid means they can't live in NYC?
