For the first time in Elementary history, we had a Gregson-centric episode. When a man tried to kill his wife, Cheryl, Sherlock and Joan did everything in their power to find the person responsible.

The twist in Elementary Season 2 Episode 6 was that the killer wasn't actually after Cheryl Gregson, it was just the wrong house. No thanks to Google maps!

Unluckily for the culprit, Cheryl was packing and left him with quite the memory.

The central theme of this episode was marriage "monogamy has outlasted its usefulness," according to Sherlock). To be more specific the main component of this installment was partnership.

Once again, we were shown why Holmes and Watson have a deeper connection as partners than they do as lovers.

Joan was asked to consult on a case privately, but Sherlock solved it own his own. It was only a "a palette cleanser," after all.

Unfortunately for Joan, she was hoping to solve the case without the assistance of her brilliant friend.

"It takes 10,000 hours to perfect a skill," Joan said, and she is still playing catch up, but at least doing so very quickly. Every episode of Elementary Season 2 there is something about her revelations that surprise me; she really is turning into a great investigator. It's a joy to watch her character grow.

Though Sherlock was Sherlock in how he responded to Watson being upset, the result of him making up for it was the gesture of the trunk and this made their partnership grow stronger.

Sherlock told Gregson, "I have come to appreciate premise of partnership. The very smallest gesture can speak volumes." This quote describes the relationship between our two leads to the tee.

Since the beginning, we've been given piece by piece by piece of Sherlock and how he has come to be. We've seen him give these pieces to Joan to establish this deep connection they possess.. Whether the pieces be bits of his past or cold case files in an old rugged trunk... like Sherlock said, the smallest gesture do really speak volumes.

In their case, this volume refers to comfort and trust.

Elsewhere, we finally saw more of Tommy Gregson. I am thrilled! The moment that Cheryl revealed he was her husband, I was so excited.

It came as shock to me that no one really knew about Gregson's personal life. I figured he would shoot the shit with some of his cop buddies, maybe even Bell. I'm surprised that no one knew he and his wife had separated.

Another surprise to me was that Sherlock was the one to give Tommy a pep talk to not give up on his wife, that he had a partner. The last scene when Gresgon told her he wasn't going to throw in the towel? Swoon!

I really love Gregson and I really love Aidan Quinn. He's definitely underused in Elementary.

Overall, this episode wasn't mind blowing or overly entertaining, but it was smooth - just like a palette cleanser. It pulled on your heart strings a little bit and it definitely made you ready for a little bit more.
