Proof That Sherlock Holmes And Joan Watson's Relationship Is Perfect

Sure, Joan and Sherlock are incredible detectives, but there are so many reasons their relationship is endearing to fans. Since they're around each other almost 24/7, these two crime-solvers understand and care deeply for each other. Here's the hard evidence!

Watch Elementary on CBS.

When Joan found out about Sherlock's crush on Fiona, she offers to help find out if the feeling is mutual. What a great wingwoman!

It didn't take long for Sherlock to come up with a bunch of awesome roller derby names for Watson. His pitches included: "Cyclone Joan," "Joan of Bark," and "Joan Cold Killer."

Who wasn't surprised when Sherlock's dad showed up? Naturally, a fiercely protective friend like Joan had to meet the man herself and size him up. She didn't mince words with Morland, telling him, "If you're going to be a part of Sherlock's life again, I want to make one thing clear. I'm not going to let you hurt him."

In order to keep their skills sharp, the dynamic duo competed to see who could escape from handcuffs faster. Why not combine a little friendly competition with real-world payoffs?

Even after their consultancy with the NYPD was suspended, the two vowed to stay together. Joan really meant it when she said, "The only thing that matters to me is our partnership."

It was memorable when Sherlock hooked up with a contact in an effort to extract intel about his father's attempted murder. Sherlock will certainly never forget it—because Joan won't let him!

Good friends often help you push yourself to be your best. After trying for hours to beat a video game, Sherlock handed the controller over to Joan, who won on her first attempt. Grr...

Everyone knows that a true friend will call you out when necessary. When Joan discovered that the neighboring complex owner hated the pair's noisy antics, she confronted Sherlock. Apparently Holmes didn't feel the need to respond to the several emails he had received from the angry neighbor.

Joan and Sherlock were happy to lend a hand to Detective Bell by getting him the reward money from capturing a wanted criminal. Oh, and as a result, he didn't have to spend endless hours studying for the Sergeant exam!

How does Joan get under Sherlock's skin? With a ringtone she knows he hates. 

Sherlock and Joan braved an overnight stakeout in freezing temperatures together. We all know that the best kinds of friends are the ones that stick around when times get tough—or, in this case, cold.
