Welcome (I think), Michael Hadge as Buzz Hackett. He must be one of the Hackett family that Elizabeth sold that shorefront property to in order to appease Jason's demands, despite Burke's warnings that they would ruin it.
You're probably right, although it's interesting that Buzz was short of cash at the Blue Whale. Maybe he's a poor relation, or maybe his father disapproves of him and doesn't give him much, or maybe that new motorcycle of his cleaned him out. Or maybe he's simply independent. Every time I see Buzz, he seems nicer and nicer. Is this because every time I see Buzz, I'm older and older? I noted his efforts to keep Carolyn from getting too wild. He doesn't wear a motorcycle helmet (or was there one that I didn't see?) but I think that was a few years before helmets started being required.
This subplot doesn't seem as silly to me as it did the last time I watched it; I've learned a little more than I wanted to know about cluelessness since then. But that doesn't make it any more enjoyable for me. And I always come back to the same question: If it's not enjoyable, why do it? The answer remains the same, too: everybody loves Buzz.
