A/N: This was a request from Ericks Angel15.

Disclaimer: I own nothing. I would love to own Criminal Minds, especially, but sadly I don't. I don't even own ICarly.

Reid sat at his desk, bored. They had no case, so he was just doing paper work.

Suddenly, his phone rang.

It was his mom's main caretaker at the facility.

He quickly picked up the phone.

"Hello, this is Dr. Reid. Is everything ok?"

The voice on the other end was weak, tired.

"I-I'm afraid not. You-your mom had another panic attack, only this one…she fell and hit her head really hard, and…she passed about ten minutes ago. I'm so sorry."

Reid felt tears prick his eyes.

He was so tired of losing people.

His dad had been the first, leaving him and his mom when he was extremely young.

His first girlfriend, Rachel Samson, had been the next. She had suddenly dumped him, sold her house, and disappeared.

Then he had started at the BAU, and had found a family.

Elle had been the third. One day she had been there, the next day, *Poof!* they were looking for a replacement for her.

Then came Gideon. He had left the same way his father had: A note and an empty room.

When he had finally gotten used to the new team, JJ had been forced to leave.

He knew it wasn't her fault, but in some ways, he still felt abandoned by her.

Then, Emily had died.

And now his mom. He silently wondered if anyone would ever stay there, no matter what happened.

He knew, being the genius that he was, that that was a foolish wish. People changed, died, moved- but he still wanted someone he could talk to no matter what.

And probably always would.

"Dr. Reid, are you there?"

He blinked back to reality.

"Um, yeah, um, can I…talk to you later? I need to talk to my boss about some time off…."

"I'm sorry, Spencer, but there's more."

He sighed.

"And that would be?"

"Well, did you know your mother had Multiple Personality disorder?"

Reid sat up straight.

"No, I didn't! Why didn't you tell me?"

"I was trying to protect you, but now-now there's something you need to know."

Reid shifted in his seat.

"Ok, I'm listening."

"Do you know who Pam Puckett is?"

Reid frowned at the change of subject.

"No, what does that have to do with-"

"She was your mother's other personality. When she showed up, I let her go. She-She had a daughter, Spencer. I let her take care of her. When Diana returned, her daughter would bring her back."

Reid sighed. So his sister-well, half sister probably- knew about her other disorder, but he didn't?

"So I have a half-sister. Tell me about her."

"She's in tenth grade, Spencer. And her mom left her in your care."

A/N: Does anyone like this idea? And does anyone have any suggestions? I am really nervous, so feedback is appreciated.

Pairings will probably eventually pop up, (It's in my blood!) but I am really wanting to focus on Spencer/Sam's Siblinghood.
