(S04E10) "It's always something." - Charlie

Great episode! I've always wondered when Don's team would encounter a situation right in their own building. While this wasn't on the grand scale that I imagined, this was still pretty damn good. Plus, you have to admit, right from the beginning it felt like a math problem. Two guys in a box. Sounds like the type of thing that was probably tossed around the conference room table when this show was originally developed. Sounds exactly like the type of thing that Charlie can take apart with theories and equations. And that's just what he did.
