Weak season by the standards of past seasons, but yeah the thing with Karl's friend is sad, didn't expect that character to be a sympathetic story.
The Frank/Debbie storyline sucks.
I don't give a rats ass about Ian (never have)
Karls' was great until this week. Made me sad. Really thought that dude was going to be an inspiration for Karl, but in a different way.
Lipp's storyline is good -- though I hate to see the hot professor leave

Fiona's has been Ok. I love that Gus isn't letting her off the hook.
Oh... and Kevin and V's story? Been fantastic.
