You people are a bunch of paranoid weirdoes. There's no way he could hurt his finger as a result of slipping on ice? Have you ever, you know, fallen? There are a thousand different ways Kim might have reached out to brace himself that could have a resulted in a finger injury. Weird stuff happens when you suddenly, unexpectedly slip and fall.
We should investigate? How? To what end? We send in Jessica Jones to, I don't know, try to somehow prove that Kim was lying about slipping on ice? That he was doing weird sex stuff instead? OK, so he was, and we void his contract. Then what? Instead of one or two months of Dubon and then the rest of the season with Kim, we get a full season of Dubon. Hurray? All so we can save $20 million for one season. There's not even a long-term commitment for us to rid ourselves of. And if we send in our crack team of trenchcoat-wearing, fedora-clad private investigators and it turns out Kim is telling the truth, congrats, your Steinbrenner maneuver dynamited your relationship with Kim and probably pissed off the rest of the locker room as well.
