I made the mistake (on accident) of talking to Sir Thedret at the very end of the Knights of the Nine questline BEFORE he had finished his speech. Now he's stuck just standing there with his arms out and he isn't talking and the other knights are stuck in their spots. They won't go about their business because Thedret hasn't finished his speech.

I checked UESP and they talked about the game itself bugging out at that point, but that's not what's happened. He doesn't even try to talk, just stands there with his arms out looking around. I realize I broke or caused a hiccup in the script and I was a moron and didn't save before the final leg of the questline so I'm prepared to have to replay the last 2 hours of gameplay if need be, but thought I'd ask if there was a console command to somehow get Thedret past the point of his speech and get the game to make the NPCs go back to living in the priory.

Have you tried bumping into him repeatedly, as the UESP suggests?

Yeah, and he just keeps going back to the same spot and stands there with his arms out. I guess I'll try a few more times then just start over if it doesn't work.

Just a thought, but are you using the UOMP by any chance to see if it covers this?

No, I play vanilla.

That may be your problem then. The UOP, UOMP, and USIP only fix the bugs. They don't change anything else, so you may want to grab them to see if they help.
