I love Sara/Darlene but I agree, they need to scale back on the soap opera aspects of Darlene's romances.
A few light funny family focused eps. And the constant references to what a loser family they are were overdone.
Hmm.... Hard to say. A rich corporate raider doesn't scream Labine, but he was intended for Lois/Rena, so I think the entire characters trajectory changed. I think the Brenda/Jax stuff was Guza but it was more of a happy accident than anything and Guza was into for awhile, but his complete lack of interest in Jax over the years makes me think he only cared about Brenda/Jax and not the Jax character himself.
I think Jason's accident was Labine. But, yikes, it was a lot of tragedy in a matter of months. Stone died like a month earlier? Could be Guza? Idk, I think I heard before that Clink Boom was actually in Labine's outlines for Lily/Sonny and Guza just ran with it. Not sure.
