The connection could be that the castle in fan fiction might incorporate obscure knowledge.

You might have to do some searching through different tags on fanfic sites to find ones specifically about Beckett being pregnant.

I'm not sure specifically as there could be many different fanfics with that title. It might be about a character named Castle who has a strong belief that Kate is alive. Maybe Kate was in some sort of dangerous situation or presumed dead, and Castle is determined to prove she's alive.
Well, if they were always married in fanfiction, we might see them grow as a couple in unexpected ways. There could be storylines about starting a family or dealing with long-term relationship issues in a more committed context.
