Perhaps one of my favourite episodes, this one was excellent on two fronts. This little side story with Bell adn Watson was very interesting - I loved how they executed it and the ending was ultimately sad yet fitting. I was excited by this storyline without the main storyline but the main storyline itself was amazing.
I loved the main case - it had everything from an interesting contraption worth millions to sabotage and murder and whistleblowers. It was just a complete case.
Well executed and edgy - one of my favourite eps of Elementary!
