While searching for a matrilineal bethrothal to my daughter to integrate the karling bloodline into my dynasty I happened to notice that one of the children i could betroth is the heir to the Kingdom of Francia. I was shocked to notice that I could so easily get my dynasty on the throne of francia if things went right.

Looks like it's because he's in some random person's court who doesn't care that he's the heir to west francia, rather than the actual West Francian court.

He's also already not the same dynasty as the current king. That might be a factor too, I don't know.
