I would love love love for them to hate the people the other person dates and undercover work would just kill me dead with joy.

Bulletproof trope. I LOVE THAT TROPE. I HOPE THEY ARE BOTH TOTAL ASSES TO THE OTHER'S SO. THAT IS ALWAYS AWESOME.

I love that there is so much we don't know about their backstories and I think you're absolutely right that their self-directed anger brings them together so very well. One of my favorite moments is when Watson remarks that there's no mirrors in the house, that Sherlock can't even look at himself because of what he'll see, and I think that's something Watson feels on a similar level.

I get the feeling she's a mirror for him as much as he is for her, which probably is also another reason both of them were combative with each other. Granted, Watson retreated into extreme professionalism whereas Holmes went for sarcasm, but it's the same thing.

I already started writing an AU after watching the pilot twice, because this has dumped a whole lot of feelings on me. I can only hope that the show remains as character focused as the pilot.

Dude. That's fast! Good luck!
