So I rewatched the last trailer, and there is a shot of one of the Viltrumites getting hit, with a pink background behind him. Almost all other shots were from episodes 1-2, so it’s fair to assume only parts of part 1 were used in this trailer.
So considering Nolan is one of the most popular characters, considering that this season will feature the VA for battle beast, and considering part 1 needs to end on a cliffhanger to keep hype alive for part 2, I am guessing that episode 4 will have the big brawl in space.
Episode 3 should have the thraxa episode since there is literally nothing else too add within the adaptation that hasn’t already been adapted into season1,Unless the make they try to stretch out some stuff like the africa adventure and the science dog thing in episode 3 and make episode 4 Thraxa but i feel it just makes more sense for episode 3 to be thraxa and episode four to be the fight between mark and levy.
