User blog comment:TimeShade/The Crisis Has Arrived/@comment-3221148-20191210004549

I tweeted @ Marc Guggenheim regarding the canonicity of the shows/movies with cameos to the shared multiverse. Folks in the comments there telling me he confirmed it in an aftermath discussion. I'm sorry, I haven't got time to catch up on that for now (in fact, I just caught up on Episode 1 of the Crisis).
