Tommy Collins.

Jenny Klein.

Sarah Baker.

Who is next?

"Me?!" Olivia shrieked. "You think he's coming after me?!"

"You're our sister," Sam pointed out. On tenterhooks, the three Winchesters sat around the library table in the bunker. They were waiting for some kind of clue, some sign of who Crowley was going to target next, and the anticipation was getting to them. Both the brothers had cleaned out all the beer, and Olivia had downed seven cups of tea in two hours while furiously digging for clues in her nearly three dozen books around her spot at the table. After a little deliberating, Sam landed on (what he thought was) the obvious answer. Olivia, on the other hand, scoffed.

"He's not coming after me, Sammy," she said without hesitation, "I mean, I didn't exist until just a few weeks ago. He hasn't even seen me in this reality. And I wouldn't have dealt with him since he killed… ahem. Since Meg died." She took a long gulp of her tea and Dean found himself wishing she would let him spike it. Ever since Tommy had been reported killed, she'd been sleeping less and inhaling tea more, but nothing seemed to make her feel better. But she said she hadn't touched a drop of booze since she was sixteen and Dean let her have some of his whiskey, so he knew she'd know if he did.

"How can you be so sure?" Sam asked, a little frustrated. Not at her, just at the whole situation in general.

"He doesn't know I'm here or who I am, just like everyone else," she stated. Sam sighed. Integrating Olivia into their lives had been a challenge. He and Dean had a rhythm to solving cases and, even though they loved having their sister along, they hadn't quite adjusted to having her on jobs. In contrast to her bubbly personality, she was usually fairly quiet in the field, hanging in the back like a real CSI tech would. She also insisted on doing the research while Sam and Dean went out which was a more drastic break from their routine. While it had been an adjustment, it worked well once they got the hang of it, but they could see that sometimes there were little twinges of sadness when they didn't remember something that she shared with the brothers of her memories.

It had also been hard for her to be completely alien to those she knew and loved. Neither Charlie nor Kevin had recognized her and, though she had been thrilled to see them again and had been her normal cheery self in their presence, the brothers knew that she would hide in her room at night and cry about all of the missing memories. She and Charlie had shared a longtime love of the Harry Potter and Dr. Who series, including a fanfiction they had been collaborating on, and Kevin was like Olivia's little brother. She had spent a good deal of time with him on the houseboat, so when he didn't remember her, she couldn't help but be crushed. It had perked her spirits up considerably when Charlie had christened her "Liv" and the name stuck with her brothers, but small victories didn't help with huge wars.

Then, after hearing about the deaths of those they helped - people she knew and trusted as she always kept tabs on them after they were saved - she had gone into a frenzy to try to stop the murders. This was the first time they had seen her stop working in nearly seventeen hours, and she looked it. Her sand-colored hair was frazzled and unkempt, her eyes were red and puffy, and her glasses were smeared with drops of tea and highlighter ink.

Seeing Sam sigh, Olivia matched it with one of her own. "He doesn't even know I exist, guys. I'm fine."

Suddenly, something in Dean's memory clicked. Right after they had returned to the bunker and grounded their sister, Dean had gotten a text.

From Crowley.

Panicking, Dean fumbled in his pocket and yanked out his cell phone to look at the message history while Sam insisted, "We don't know he doesn't know, Liv. Crowley's surprised us before, you know that." Olivia rolled her eyes.

"I do, and I also know that no one remembers me. Not Charlie, not Kevin, not Metatron, not-"

"Crowley remembers you, Liv," Dean said lowly, and his siblings both whipped their heads towards him in shock with a chorus of "WHAT?!"

"He knows you're with us," he clarified ominously and pushed the phone over to her, "Tinkerbell." Olivia paled; she obviously remembered that name. She clutched at the phone and read the message over and over.

"No no no no dammit no…" she mumbled, standing from her spot at the table and beginning to pace, "The ONE PERSON I didn't want to remember me knows me! Damn it!"
