I love the way they're committed to their grisly and important work but in the off-hours they're building this really sweet and rather domestic relationship. The scene where Molly is confused and blown away by Lestrade fixing stuff around her house is really well-done. You have completely sold me on this pairing, and I really hope it catches on in the fandom.

I'm highly amused by Molly's decision to keep Sherlock out of trouble while John is otherwise occupied. Apparently it takes a village to raise a Sherlock.
