Nurse Jackie 9 p.m., Showtime 2
I love the supporting cast of this show, but Merritt Wever as Zoey has to be my favorite. Wever’s timing is perfect, and unique. Her character isn’t like Phoebe on “Friends,” but like Lisa Kudrow, Wever has developed her very own comic rhythm of delivery. This season, the writers are giving Zoey more screen time than ever. After getting confident enough to live with and take care of Jackie, she is ready to fly off on her own, take charge of medical situations, and maybe even have another romance.
