From my limited knowledge of Lloyd, Lloyd > Rean.
It was great beating up Rean lol. Very interesting making Rean be the enemy for the chapter.
what do you feel has been spoiled regarding Ao? All the game does is show some things without any explanation whatsoever i feel. Except for a character outright saying they travel between them.
But Ao certainly spoils more, actually the Ao spoils the whole ending twist.
Since you're already here I'll leave a short description of what Ao actually spoils for CS1 and 2.
The trade conference takes place, though Towa is nowhere to be found and a nameless terrorist who presumably is Gideon dies. Some time later Erebonia decides to nuke Crossbell for their bank freeze. They actually decide to fire on the city for real with the guns (after CS1 ch5) and had their shots blocked by Crossbell's weapons. Then Garrelia gets hit. Then the story continues until the tree shows up and vanishes and in the very end of the game the ending narration spoils that Osborne is alive, the nobles lost, Crossbell gets invaded, and gives a date for its liberation with some motivating shots of the cast covertly fighting against the empire.
All in all it's not much that gets spoiled but then again CS2 doesn't have many real spoilers.
How much of Crossbell declaring independence and then the President getting arrested was important to the story of Zero/Ao? It felt very major reading about Crossbell from the news and having that plotline referenced a lot toward the end of CS2. Not much of the Azure Tree stuff feels spoiled in CS2 other than Ouroboros being behind it and the tree going away by the end.
