I feel it's more that, once Battler arrives at the truth, he decides it unimportant because 'without love it cannot be seen' or whatever. His story written for Beatrice is what he wants to remember, and Battler... well, he's incredibly selfish. He isn't a character representing the theme of truth; he's flawed and swayed by his emotions and attraction to Beato. Plus, the first four episodes were him not realizing the Shannon/Kanon/Beato "how do I hold all these personalities" pile-up and treating it as traditional mystery, as opposed to Yasu's Personality Disorder Island 1986. Ends up being a very personal story to a lover he 'killed himself' (with the Hachijo personality) for.
Plus the last time he tried traditional explanation Erika locked him in a room for thousands of years where he mutilated himself. Odds are that's a pretty good point of reference for what Ange could go through. Different scenario, of course, with a logic error compared to definite truth, but altogether hopeless.
I feel it's more of a dynamic between Red and Blue, with Red representing a terrible scenario and Blue representing all forms of hope. Maybe I'm corny like that, I enjoyed Episode 8 outside of the 'yeah well Red Truth isn't definite anymore if you're deluded enough', but that kind of goes to the theme of 'truth is what you make of it and can be twisted by the person expositing it', as was already proven when it was introduced ( "You are incompetent!" ). But now I just feel like I'm rambling and trying to think of exactly why I liked Battler in Ep. 8. Because I really did, it's just difficult to explain exactly how.
