So he was going to show up at the wedding and make an unexpected announcement. He would say, 'I've decided I can't be friends with any of you anymore, because clearly you can't trust me, so I need to go my own way. I'll do my job but that's it and that's all that's ever going to be.' And then he would walk out again. And the people there were going to go 'Whoa, what does this mean?' Then we were going to play Odo completely different for the rest of the season."
Though not 100% satisfied with the way it was handled, I'm glad they didn't do that. First off, weddings being interrupted by whatever is such a played out TV cliche. Secondly, it just seems way too drama-queen for Odo.
