Here's a quick transcript I made of the one part. When Josh brings up the DCU combination, Matt is kinda just being like, "Yeah anything is possible", and Josh keeps pushing the topic with Matt just keep being like, "Yeah anything could happen." lol
It does feel like Court of Owls and/or Hush is the obvious direction to go, either here or in the theoretical trilogy conclusion. (Hush to me is overrated and not great, but if you wrapped that into the Court, it could work as source material for a dope The Batman sequel.) I also maintain my “the last one should tell the story of this Batman taking on a Robin” take. Probably not Dick, since there will probably be a Nightwing in that share universe shit plus that Dynamic Duo movie, though the circus crime angle would likely work well. Maybe do a big swing, like Carrie Kelly or whatever?
I think Part II should reveal whatever villain Batman was dealing with was funded/controlled by the Court thus revelaing them as the main enemies for Part III
