Remember this... Sydney and Vaughn throw a birthday party for Weiss. Weiss and Nadia hit it off, talking about Weiss' smile. I love this real life moment between Sydney and Vaughn- gossiping about their friends. It's sweet and intimate and a testiment, not only to Sydney and Vaughn's relationship, but Jennifer and Michael's ability to be confortable in moments like this.
