Obvi Nicole and Sam are "just friends", but why wouldn't Lindz (who was also good pals with Nicole - at least once upon a time) be invited to the girls' night out?

In fact, Samantha left Lindsay home alone at her house to take Nicole out to Matsuhisa (where we're sure the preggers Nicole avoided sushi). Did the gal pals just need some time alone to b*tch about their relationships?
