I wish they would at least once bring Leviathans back. They are still out there but the writers seemingly forgot about them. Instead of next week's "The chitters" they could make some Leviathan episode. The Leviathans might have some things to tell about the Darkness. Wasn't there a monster army mentioned in "Baby" ? Levs are the strongest monsters - why not bring them back as the leaders of the monster army. So we can see Amara finally crushing them all.
