I have to say, the method used by Odelia to persuade him obviously had a higher success rate than Clinton's handwritten invitation. Odelia hadn't seen Tommy for a while, so how could she miss an opportunity to meet him? Tommy also couldn't tolerate someone else escorting his girlfriend in public.
So the thought of having to do battle with Odelia tonight, as well as concocting a conflict for the ever-interfering Bill to mediate at the party to ensure Jeff wasn't affected, while still ensuring Bill's intervention was effective, really irritated Tommy. These two tasks combined not only required a lot of physical energy but also drained a lot of brainpower, squeezing him dry.
