There are two things that bother me.
First, we didn't see Kate and Anthony announce the pregnancy to the family. I missed that part, it would be better they showed that instead of the Mondriches or a threesome.
Kate and Featherington girl are pregnant at the same time, or the sister should be further along. Yet at the end of the episode they're not even showing, but a few weeks earlier Kate has such a visible bump.
Edited to add, a friend told me Kate actually announced, I totally missed that part
