bus crash

After seeing tonights episode, I really think Darius and I are onto something with our theories about who's responsible for the bus crash. However, now I'm wondering if the writers are throwing us a red herring with Beaver's curious reaction (or lack of reaction) toward Mac. Is Beaver the one who's gay and not Dick, as Darius theorized? Beaver's real estate dealings play a role in the Mayor's incorporation issues, so I could see him doing it just to make the Mayor's life miserable. Maybe both Dick and Beaver are working together on something for once?
