"I dunno if I'd use the word 'evil,' but yeah, I think - I think she's the root of it." Not exactly an unpopular opinion, but voicing it aloud helps him feel like he's got a goal, maybe. The illusion of one, anyway. "And I think that, if we wanna make any headway with the Mirrors, she's gotta be our target."

How does one even begin with that kind of thing?

Hell if he knows. She's not easy to get ahold of, and the Mirrors are pretty loyal to her - and those that aren't are willing to fake it for their own personal gain.
