No, thankfully the next one is still next Friday morning. They are just tossing a few extra 'Riddles in the Dark' sessions in to discuss the final release of the extended edition of the final Hobbit film.
As
ouzaru points out, Melkor will be absent in Utumno during this time (right?). But Melkor clearly does not just sit in Utumno biding his time, as he is out recruiting Ossë and no doubt causing mischief.
The guilt/suspicion seems to have fallen to the balrogs, but pretty much everyone knows that Melkor is fairly guilty of the disharmony. So, the tension among the Valar remaining to go off to found Valinor...would be the suspicion that some of their number are still loyal to Melkor and would possibly be recruited to his cause, etc. This would lead into the fall/repentance of Ossë and the near-fall of Aulë. I think that suspicion could easily fall on Ulmo, as he is such a loner and does his own thing. The Valar who clearly do not abandon Middle Earth are Ulmo and Oromë, and to a lesser extent Yavanna.
I don't really like the idea of the Valar mistrusting each other. I am hoping that, really, we'd have a disagreement about what should be done over Melkor's obvious problem. Some of them might want to confront him directly, using force to constrain him (ie, war!), while others may be more of the opinion that if everyone just keeps to their own devices, everything will be fine, just fine, really....
Another plot point that needs to happen during these next few episodes would be the introduction of Mandos and Lorien. Námo and Irmo should be fairly minor characters prior to this - with Námo declaring Manwë to be their leader in episode 2, and then mostly staying out of the squabbling when Melkor tries to take charge, re-emerging as an important figure later on with the prophecy of the coming of the Children. One of his character traits is to never explain anything, merely make statements of truth that his listeners might not understand. So putting the emphasis on Irmo now might be a good plan. But anyway, so now we have domains for these two (and their wives), and we can maybe give some explanation of why they are SO tied to their lands that their names are synonymous now.... We can also introduce Melian and Olorin with Irmo and Este. Perhaps the 'peace of Valinor' can be represented by their quiet gardens, in direct contrast to Ossë's chaotic and violent rebellion? Uinen should be instrumental in winning Ossë back to the good side, of course.
By the time we reach the creation of the eagles and ents, ALL of the minor characters should be introduced. We can't be introducing more characters as we move into the War and the finale. So, who do we have playing key roles in this season thus far?
Episode 1 - Ainulindale - Introduction of characters, but doesn't count because it's really a brief introduction of Arda. Introduction of frame characters: Elrond, Gilraen, young Estel.
Episode 2 - Shaping Arda - Introduction of major Valar = Manwë, Varda, Aulë, Yavanna, Ulmo, Námo...and? Should include Nienna and Oromë to round out the Aratar.
Episode 3 - Melkor's backstory - Melkor, of course, with some emphasis on Varda and possibly introducing the Valaraukar (balrogs)
Episode 4 - Melkor among the Valar - introduce Sauron/Mairon now to show that switching allegiance is possible. Curumo stays loyal of course.
Episode 5 - The one where Ungoliant kidnaps Nessa - Tulkas, Nessa, Ungoliant as major characters
Episode 6 - Destruction of the Lamps - Balrogs and Arien should be key players
Episode 7 - Valinor, pt 1 - Ossë, Uinen, Lorien, Estë, Olorin, Melian?
Episode 8 - Valinor, pt 2 - If Yavanna hasn't lit the Trees yet, she really should!
Episode 9 - Aulë, put that hammer down!
Episode 10 - Eagles and Ents
Episode 11 - Prophesy
Episode 12 - And so, we shall go to war
Episode 13 - War to Begin All Wars
Who do we need who hasn't been introduced yet? For instance, does Oromë have Huan yet? Oromë has his big time in the spotlight in season 2, but he should surely be around as a background character in much of this. Will Eonwë just sorta be.....there? We haven't even barely mentioned some of the Valier yet. I am not suggesting they need a whole episode or story arc or anything....but they do need to be there: Vana (Oromë's wife, the Ever-Young
), Estë (Irmo/Lorien's wife, Vala of Rest, she mostly sleeps on an island in Lorien, so......), Vairë the weaver, wife of Námo/Mandos who has elements of the Fates about her. We are investing a good deal of screen time in introducing Nessa, one of the Valier who will (potentially) have no further role in this story. Should we be instead investing in Nienna?
