When I first started to watch the show last summer, I thought I was the only one in my house who watched it. But then a few months later, I found out that my brother started to watch some of it while he was away at college.
He only seemed to be a fan of Shawn & Gus when I first found out, but over time, I've converted him into a fan of Lassiter.
And he seems to have taken more notice of characters like Juliet and Karen Vick too (he used to claim that those three didn't appear very often and weren't a big part of the show), so that makes me happy. Now he and I have been watching my Psych DVDs and the new episodes together.
