It also meant they couldn't develop any side character. Josie, Regie, Kevin could be actual characters now.I'd take 13 episodes over 22 episodes. 13 episodes was just right for Riverdale, and 22 episodes might stretch things out a bit too much and include more filler.
But good to hear it starting up back in October. Thought Season 2 would come back next year, but color me surprised.
