Greetings, commanders!
Soon the big story ark will conclude. What do you think will it end with?
Personally, I think Salvation and his team will die just like the team of Proteus in Trapezium Sector YU-X c1-2 1a.
Thargoids will not be destroyed completely
My pet theory is that Salvation/Azimuth are playing us for fools and never intended to destroy the Thargoid in the first place. Azimuth was very interested in Human/Thargoid hybrid technology/ships and the Thargoid are the only place where they can get these. Maybe Salvation/Azimuth is trying to "wake up" the Thargoid motherships for further research purposes and uses this entire "Let's blow up the Thargoid" message as a bait to generate support from the Pilot's Federation and the Superpowers (who would probably not help Azimuth if they were to know the truth). In this day and age of story writing, anyone with a name like "Salvation" is telegraphing being the bad guy from ten lightyears away.
According this theory, tomorrow we could witness Thargoid Motherships in space for the first time (either inert and "claimed" by Azimuth or fully operational and angry at us).
