Also possible, yes. The way he almost acted like a robot at the end was a dig at him being an NPC, I thought. But it could also be a dig at Paladins always being straightforward, literally. That's the great thing about the movie, many gags work on several levels.
It's really a very good movie. The best thing about it is feels like an actual session being filmed. You can almost tell when the rolled a 0 and when they rolled a 20.
