WHAT THE I DON'T EVEN.
By the way, when Olivia mentioned the nursery to Peter, she was indicating that she wants to have adorable babies with him, not that she's already preggers, which a surprisingly large swath of fandom seems to assume. I think that would have garnered a little bigger reaction from Peter. And then she was drinking wine later. So... yeah.
As for the rest of that episode... I can't even process right now :\
