Brothers and Sisters: Preview of Episode 4.07 "The Wig Party"

If the title isn't much of a clue, then here's the preview for tonight's Brothers and Sisters episode.  "The Wig Party" brings the Walkers together once again, but it won't be all fun and games for the family.  More drama's heading our way as usual.  In addition to a smidge of romance, of course. "The Wig Party" has Nora (Sally Field) meet a new man in her life.  She's taking quite a risk with this guy, since he's an oncologist in the hospital where Kitty (Calista Flockhart) is being treated for cancer.
