Unless Nikki has just accepted that Victor has completely lost his mind and has accepted him disappearing to "follow the yellow-brick road", I don't guess she has any reason to get into it with him. She is just glad that "The Crazy Mustache" is finally back home. And Victor put Hope right in the middle for drama. What kind of crapola is that? And wasn't Victor awfully relaxed about John's death? I was surprised that the writers had Victor and Nikki just show up at the Abbott's home completely without warning.
This show is getting as stupid as The Bold and The Beautiful.
