So maybe if AoS is moving to the later time so they can go darker, they'll replace its older scheduled time for something new, like, "Origins of SHIELD".
AoS is preceded by a 2 hour comedy block :
8-8:30pm: The Middle
8:30-9pm: American Housewife
9-9:30pm: Fresh Off the Boat
9:30-10pm: The Real ONeals
and is being scheduled against NCIS: New Orleans
& Chicago Fire
on CBS & Fox. So AoS has no lead in and is up against stiff competition in the time slot, somebody is looking to kill the show off and there is no replacement show on the horizon. Cloak & Dagger
is supposed to be on ABC's sister channel Freeform sometime next year, but news about Damage Control
on ABC has dried up where as Powerless
has got a season order on NBC. Don't get me wrong, I think both of those comedies are going to be pretty bad, have very niche audiences and will be cancelled mid-season but ABC seems to be moving away from producing Marvel based content.
CW have announced that they'll be doing a 4 night\way crossover of all it's DC shows, so that first week in December is either going to fantastic or a train wreck.
