I found the claim that someone had "informed" Monard Law as to Ben's activities silly anyway, given that one of his colleagues from Mondard had already been involved in the case.

It's very probable Ben fell out of favour with Monard due to not dedicating enough time to them, and decided to move on. If "fired", then not the kind of firing that stops him getting another job, or a reference.

(And to be honest I can't see a law firm doing that anyway. Reputation for them is extremely valuable, so they either get rid of a wayward employee quietly, or throw the book at them in the most public way possible to show everyone they're purging their ranks.)

No scandal here. AD's been duped.
