What's Your Favourite Brothers & Sisters 2 Storyline?

The second series of Brothers & Sisters came to an end in the UK last weekend, but I'm still thinking about those Walkers. As a way to ease the temporary loss of one of my favourite fictional families, I've been thinking back over the season and trying to figure out my highlight. I'd love to know what you think, so tell me: what's your favourite storyline of this season of Brothers & Sisters?
