ABC's Brothers & Sisters ended its fifth season with an eventful episode. Sarah (Rachel Griffiths) marries Luc (Gilles Marini). Kitty (Calista Flockhart) learns she is pregnant, and wants to keep the baby, despite the health risks. Saul (Ron Rifkin) accepts a proposal from Jonathan (Richard Chamberlain). Tommy (Balthazar Getty) puts in an appearance. And Sarah makes peace with her father, Brody (Beau Bridges).
While season five has certainly been a weak season overall, there are some really great elements in this episode to remind viewers of how good the show used to be. The drama in "Walker Down the Aisle" is realistic, and none of it comes out of left field. The wedding actually goes off without any major hiccups. The characters mature and relate to each other in ways they haven't in awhile. And there is some real closure, as well as setup for new story, should the show get an abbreviated sixth and final season, which looks likely at this point.
Sarah dealing with Brody is the biggest development in the episode. While she has only known for a short time who her biological father is, Sarah has been in denial, wanting to pretend Brody doesn't exist. Yet, like a real father, he stays near, not pushing, but giving her plenty of opportunities to open up to him. She finally does, just before the wedding, and he confesses to always keeping tabs on her over the years, having suspected the truth.
While the Brody story did come out of nowhere, William Walker is established as a not-very-good husband early in the show. As such, it isn't totally out of line for this whole mess to pop up years later. While Sarah, especially, has trouble letting Brody in, her reactions are authentic and in character, as is her final acceptance of him. Now that Sarah is letting Brody in, he is free to finally be with Nora (Sally Field), his true love. Brody's story is sweet all around, and he's a wonderful addition to the cast. If anyone is promoted to series regular for season six, it should be him.
