Just watched David's episode. While I was never crazy about the series, It was fun seeing him in a major role. David played a college writing teacher who was coaching Willie on his script writing and started dating his sister Nancy. When David got critical and snarky over both the script quality and his abilities, it devastated Willie enough to want to give up writing and cause friction that Nancy didn't want to see him anymore. At the conclusion, turns out David's character was actually projecting his own failure as a playwright and after explaining things to Willie, Nancy decided to go out with him again. David looked quite comfortable in the role and almost looked like he just walked off the set of Night of Dark Shadows - plus he got to smooch with Meredith Baxter.
