I loved Patrick's reaction(s) to some of Dorn's comments/corrections. They all had very good, fun, chemistry. I think that's mostly why the show worked so well it's a chemistry I really don't think any of the other casts had.
It's true, and Marina even alluded to it in discussing her lunch with Majel, Kate, etc.
They had a very special chemistry that, agreeing with Levar, was really lucky to have worked out so well.
