- Jossed. Alpha remains a villain until his last appearance, gloating that he and his brethren were employed by Morando to target Vex's family so he'd be swayed into helping Morando bring down House Tarron, after which Vex kills him.
While the second possibility is very unlikely it is still strange that despite clearly having an army and also have a law which dictates punishing treason with death that they wouldnt go after the Brotherhood.
So perhaps at the very least the King and Queen arent as good of rulers as some believe. And the soldiers who helped overthrow them arent just doing it just for power.
Another reason why this is possible is that it would create another obstacle for the main characters. Since the King and Queen will have to regenerate eventually, if they really are as competent and good as they seem then it might lower the stakes and take away agency from Aya and Krel (who would likely defer to their parents on what to do).
If they are bad or at the very least dont make the best choices then it would give Aya and Krel a reason to defy them thus allowing them to be able to take charge and fight their own way.
(On a side on I just finished binge watching the entire series for Trollhunters to this one, a few minutes ago. And it was.. well, GLORIOUS! Also sorry if I got anything wrong in spelling or information, its late and I just finished binge watching the series.)
Col. Kubrits and her agency at Area 49-B - who are established as being xenophobic crusaders - will see all evidence of the troll-invasion and the alien's presence and will set up shop there. Not only will she be the one responsible for all suppression of the invasion from being broadcasted outside of the town to the rest of the world, but she will also establish a draconian hold on the town. Arcadia might even be Quarantined with Extreme Prejudice similar to the likes of Seattle from Infamous Second Son and Gotham in Batman: No Man's Land. People needing to pass through detectors as they walk into school or move to different parts of town, unlawful searches and seizures, agents with guns bullying the populace with complete disregard for the rights of the citizens. The aliens and Aaarrrgghh!!! will be in-danger, their allies doing everything they can to keep Kubrits from discovering them. Oh yeah, things have just become Darker and Edgier!
A perk would be the reveal of James Lake Sr. showing up, revealing that he was not being unfaithful to his wife, but rather was called in due to issues of national security and has now set up shop in Arcadia out of a twisted desire to protect his wife and mysteriously absent son.
