Looking into the near future for a bit, are there plans for a session regarding the villain storyline of Season 5? After my post about the
prophecy of Huan, I'm growing more and more sympathetic to the idea of making it a part of that storyline (and the Dagor Bragollach part of the Season which we will get to eventually; when the Pass of Aglon falls, Celegorm and Curufin will abandon it to arrive in Nargothrond at the start of Season 6).
A few scenes about Huan don't really fit anywhere else, in my opinion; Celegorm is pretty irrelevant even in the debate around a possible assault (we could change that, but it seems like it's already complicated enough) and Luthien isn't involved much this season either - also, Huan's love for her in Season 6 is spontaneous and on first sight. Beren could work, but he is introduced very late in the season and him knowing Huan early has implications we would need to be aware of. On the other hand Sauron, Thuringwethil and Draugluin all meet Huan at Tol-in-Gaurhoth while Morgoth starts to prepare Carcharoth as an anti-Huan door guard - they obviously know Huan's fate, so they and the audience need to learn about it.
