Btw call it edgy or whatever but I think that if there is keys there should be 4
Pre-Awakening: from EP 1 to 4, saying this is "pre-solver" is wrong, as Uzi always had the Solver active as early as Episode 1, in the battle against Uzi vs J, you can even see 1 frame of the Solver flashing in Uzi's visor and then by the end of the episode, the Solver is truly active. To be clear this is key for Uzi before she gains wings and a tail
Post-Awakening: from EP 4 to EP 7 nothing much changes aside from the fact Uzi has wings and a tail, and the fact the Solver is at constant risk to possess or mess her powers up.
Pre-Apotheosis: from EP 8 (before Uzi becomes Solver's host) basically the same as the third, except now Uzi has completely got ridden of the Solver's influence for good (you could also add enhanced hacking and resistance to it for Uzi considering that when Cyn tried to hack her, she was almost hacked back)
Post-Apotheosis: From EP 8 (after Cyn's death) this is basically Uzi as the main host for Solver, and also with her new Eldritch body
