My question is this: there is one scene where Rollins is at her computer and is talking to Fin. Rollins says something about "think anyone will remember a 2 1/2 year old case? What are the odds?" Fin gives her an odd look, and she replies "Easy, easy....just an expression".
What is she talking about? What's the expression, and why would Fin be pissed about it?
Also: Is Benson's brother a nutcase, or what? Something tells me this guy is gonna meet an unhappy demise.
