I'm filling this prompt given by my Cumberbatched friend :) I don't usually do crossovers but this is just too good to be true.

"SHERLOCK!"

Oh God. It can't be her Please not here, in front of John. No. Please. Oh God no.

"SHERLOCK!"

I slowly turned around taking in the bouncing blonde thief. Great. She hasn't changed, not one bit.

"Good to see you, Parker. Last time I heard you were in Boston." I can almost hear John's eyebrows raise, face turning into that adorkable quizzical expression. Yes, I'm aware that I just used the word, adorkable. I should really stop reading all that livejournal stuff about Doctor Who. Although that stuff isn't half bad.

"Actually still in Boston. We just had to make a run in London. It's so good to see you! After what 3 years?" She threw her arms around me. I relaxed for a bit. This is Parker, I remind myself. You trust her, remember? Right. I smiled down and wrapped my arms a bit tighter around her. God, how I miss having Parker around.

"It's actually 2." I say into her honeycomb hair.

Cough. Right. John. I looked at his expression flash from anger, to envy, settling down on amusement. Parker released me, pulled my head down and ran her fingers through my hair.

"You need a haircut."

"I remember." Smiles exchanged, I pointed to John. "This is John, my umm partner, colleague, friend."

"Like skull?"

"His name is Henry."

"I like skull better." Uh oh. That grin.

"Yes. Yes. He does seem to respond to skull more than Henry."

Cough. The bulky man standing next to her. Military. Stance, at least NSA. Hates guns. Hidden pocketknife in belt. No other weapons, which means that he likes to use his hands. Heavy boots. Walks a little bit bow-legged. American. Southern. Good heart. Ah, a southern gentlemen. Hands. Callous. Too many bruises. Judging from Parker's new bracelet, he loves, well at least fancies her. Not good.

"Sorry. Right. This is Eliot Spencer. This is Sherlock Holmes."

"Parker can I talk to you alone… NOW." I pulled her to the side, out of earshot.

"I can't believe you're here Sherlock! You know I tried to find you after you changed your address."

"Parker. Parker! What are you doing with that man? You know he's an assassin right? He's dangerous. Stay away from him. I'm telling you that now. You hear me? Get away before it's too late. This time I'm serious."

"If you're half as smart as you say you are, Sherlock Holmes, you would know that Eliot is just a big teddy bear. Yes, he kills for a living. But that's the past. He's different. We are all different. He protects us."

"You love him. Don't you?" I wasn't jealous. No just protective. That's different things.

"No. Never. I can't." No please not that face.

"I'm sorry Parker. I didn't mean it that way."

Gulp. "Yeah. Sure it's fine." Eyes. Hands. Definitely not fine.

"Parker. Look at me. I just want to make sure you're okay."

"By running."

"Don't. You know I had to. It was..."

"For my own good. I know. You said that before. Many times."

"I'm sorry. I know words don't mean much. But you're here. And coincidentally we finally ran into each other, after 2 years. At least let me take you and your… group out for dinner.' God how he hated her for making him so uncomfortable. For making him care. For all the guilt.

"I thought you didn't believe in coincidences."

"No I don't. You must have tracked me down." Same grin. He forgot how much he loves her.

"Common. Let's go. Before Eliot and your John gets into a fight."

"Right. Sure. He's NOT MY JOHN. PARKER! Parker?" Damn it, that girl was fast.
