Someone mentioned quite early on the final was free to watch on Youtube. I'm not seeing that anywhere. Also doesn't seem to be free with TNT basic either.
According to AI (I know) it is no longer on YouTube and hasn't been since 2023. You can log in to Discovery+ and watch it free on their app if you have a smart telly, apparently. Not sure how up to date that is as HBO has taken a lot of Discovery+/TNT stuff, so maybe try the HBO app, too, and hope that one has a free option.
Hopefully there will be some confirmation before Wednesday.
