This story sort of popped into my head whilst I was watching fan vids on YouTube. Who knows where this will take me but I hope you enjoy.

Plz R&R

"I just got your messages. What happened?" Asked Morgan as he entered the waiting room.

"She was found with a gunshot to the chest. There were no witnesses."Replied Hotch in his usually no nonsense tone.

"I asked her if she wanted to hang out tonight but she said she had a date and I laughed at her. She took it the wrong way and walked off."

"Don't beat yourself up about this Morgan. I tried digging for details earlier but she wouldn't give me anything apart from they met at a coffee shop." Said JJ.

"I need to be doing something. I can't just sit here and wait." Said Derek as he began to pace the waiting room.

The tension in the room grew and grew until a Doctor came in asking for Ms Garcia's family. The whole team rose as one.

"Oh." Said the Doctor. "I take it you're not blood related?"

"No she doesn't speak to her brothers and her parents died when she was a teenager." Replied JJ.

"Ah. Well we are having trouble controlling the bleeding and we are running out of Ms Garcia's blood type. None of you here happen to be AB-?" Asked the Doctor.

"I know that blood type." Thought Rossi.

"Sorry I'm O+." Said JJ.

"Same." Replied Reid and Hotch.

"I'm O-"Said Morgan and Prentiss.

"Rossi? What type are you?" Asked Morgan.

"I am B- but I am trying to remember who I know that has that blood type."

"Wait. You know someone with that blood type. What are the chances of you knowing two people with that blood type?" Said Morgan.

"Well..." Began Reid.

"It was a rhetorical question kid. I am just trying to point out that the odds are astronomical."

"Oh. Well you'd be right as only 0.8% of the population have that blood type." Replied Reid.

"Will you two be quiet for a moment? I think it was back in 1980. There was a raid that went bad and an agent got hit. She pulled through but she left the field after that. She was bloody lucky the bullet wasn't an inch to the right or she wouldn't still be here." Muttered Rossi.

"Rossi? Who on earth are you talking about? Who got shot?" Asked Derek. He needed his baby girl to be okay. He would do anything to make sure no harm came to his best friend.

"She could be here in 20 minutes. Is that too long Doctor?" Asked Rossi.

"No. We have made an emergency call to the blood bank but they can't get the blood here for at least an hour. We just need to buy some time."

"Right. I'll be back soon. I need to call in a favour." Said Rossi as he quickly left the waiting room with his phone already ringing.

Deciding to make sure his friend was alright, Hotch followed him out into the hallway.

"Listen it's me." Began Rossi. "I know it's late and I'm sorry if I woke Tom up but I need to call in my favour now."

Not being able to fully hear the other side of the conversation Hotch was at a bit of a hindrance but thankfully Rossi had his phone volume quite loud.

"What do you want?" Came the very familiar female voice.

"Your blood type is AB- correct?"

"Yes. Why do you know that?"

"I remember from when you were shot in the 80's but I will explain everything once you get here."

"You still haven't told me where here is David." Came her curt reply.

"GW Hospital. Surgical floor. Please get here ASAP."

After a couple moments of silence Hotch saw Rossi deflate with relief as the mystery woman must have agreed to come.

"Are you going to explain what's going on Dave?" Asked Hotch once Dave was off the phone.

"Hotch. How much did you hear?"

"Enough to understand why you didn't want any of us to know who you were talking to."

"She does have a heart you know. It just gets buried underneath all the red tape she tends to hide behind." Replied Rossi.

"Will she do it?" Asked Hotch. "Will she help Garcia?"

"Yes. No doubt about it. Just keep the team away from her until after she's helped Garcia as they might get the wrong end of the stick as to why she's here."

"No problem. Why don't you go wait for her at reception and I'll let the doctor know so they can get set up for when she arrives." Replied Hotch as he left to go do the only useful thing he could.

Have you figured it out yet? Dun Dun Dun.

Might not be who you think it is :)
