Oh, man, I'd definitely be interested in doing something wrt keeping order! Since Jack has lucrative connections in terms of knowing who criminals are considering he works at the Intake facility, he could probably point Fenris in the direction of some likely forgers or something like that? He'd probably be interested in coming along as Fenris pursues people too, even though that's technically outside of the scope of Jack's job. He's uh. Thorough...

Also on the established CR front, Fenris and Jack have probably had dealings before just generally speaking, but I'd even say Jack probably likes Fenris, which I'm sorry for lmao... Because I can only imagine that Fenris would not be a fan of Jack lord.
