Another happening within this season is the dynamic between Sam and Naomi who by the finale realize they can no longer be friends as well as the deepening romantic relationship of Cooper and Charlotte.

Addison was romantically linked with Kevin Nelson (played by David Sutcliffe), a police officer, but later realized their relationship was going nowhere.

Towards the end of the season, Addison falls in love with cardiovascular surgeon Noah Barnes, who as it turns out, is married and is expecting his first child.

Archer Montgomery (Grant Show), Addison's playboy brother, also made sporadic appearances causing trouble for her and Naomi.

Violet stirred some of her own drama when she began dating Sheldon (Brian Benben), who works for Pacific Wellcare, and Pete.
