So yes Evan has some shady business he might have flailed and asked her to help keep from his parents and sister over the last decade and change. :|a

Beyond that, I'm sure she and Eileen are about to get to know each other, even if they don't just now. I think the only person who has clarity on Cadogan before the army would be Silas, but it's possible they know each other as part of the red-head brigade? Or that Cynric knows her because why wouldn't he serenade the pretty lady? Or that Rita knows her because badass gals with great tits and sharp brains?

Chives I've got nothing, though.
