AN: To answer a question…the person who said huh was Mark.

"Meredith, what's he talking about?"

"You didn't know? How could you not know? Wait," Derek paused to think, "then why were you talking to her?"

Christina mumbled something under her breath and faked a cough. Derek was blinking stupidly at both Meredith and Mark, like he was trying to picture it in his mind but something was blocking it, forcing the idea out.

"We...uh..we dated a while ago and..."

"Meredith, what's he talking about?" Derek asked, mimicking Mark.

She swayed, stumbling a little, but Christina latched onto her elbow and pulled her upright before she sink lower than the edge of the table. Mark frowned, beginning to wonder if she was seriously sick; her expression was blank and she was even more pale than usual. Christina, reading Mark's thoughts, quickly assured him that Meredith was fine.

"It's just stress. She gets like this a lot."

"Does she need to…lie down or something?"

"Nah. Meredith? Want to answer Derek's question? The one about you having sex with Mark ten years ago?"

Meredith groaned and looked up.

"Alright, alright, so I was stupid enough to sleep with Mark-"

"Hey!"

"You slept with Mark?"

"But that doesn't mean," she plowed on, ignoring both men again, "that I'm any less mad at the two of you now."

"Mad? Why are you mad at me? I didn't do anything to you…recently," Mark added hastily after seeing her expression. When it didn't soften he tried again, "You look great?"

"You," she snapped, one long finger pointed at his chest for the second time in ten minutes, "You, left me pregnant after a four year relationship because-wait a minute-I'm still unclear about the why. You," she repeated, not giving Mark enough time to breath let alone answer her question-instead beginning to round on Derek, "led me on while you had a wife and a kid waiting for you back in New York. I am not the one who fucked up this situation."

"You didn't tell her you were married?"

"Did you tell her why I left Addison?"

Mark fell silent, and Meredith brought a hand up to rest on her hip. She wasn't feeling sick anymore- nine years of anger were bleeding out of her and she was feeling strangely bold.

"Why did you leave Addison, Derek?" Meredith asked in an ersatz-innocent voice that made Mark inwardly cringe.

"Because I found them in bed together," Derek announced, almost proudly, "my bed, actually."

Meredith pursed her lips, trying her hardest to ignore her best friend's expression of gleeful shock .

"You two are impossible!" she hissed, "And Mark, don't you dare try to turn that into some kind of compliment because it's not."He shut his half-open mouth reluctantly, "I'm sick of you two already, and we've only been together for fifteen minutes!"

"Did I mention he had sex with my wife?"

"Did I mention that this entire conversation is getting us nowhere?" Mark complained, "Can't we just agree that we all made mistakes and move past them?"

"Easy for you to say, you're the one who made all the mistakes!"

"Hello-wife and daughter?"

"Shut up! Both of you, just…. God, can you be quiet for like ten seconds? I'm getting a major headache here," Meredith whined.

"You're love life is so much more interesting than mine right now," Christina observed, a smile playing on her lips.

"Yeah? Want to switch?"

"No. Thanks for asking, though."

"Well? What are we going to tell Addison?" Mark asked, after it was clear that no one else was going to.

Meredith felt her confidence deflate, and suddenly she was back to being the almost-fainting girl who was having a hard time remembering her name let alone the soap opera that had become her life.

"Oh, God. Addison," Derek moaned, "She's not going to be happy that I'm not only dating an intern, but that that intern just happens to be the biological mother of her kid."

"Dating? Who says we're dating?"

"We're not?"

"She broke up with you after you're wife showed up," Mark supplied helpfully.

Derek glared.

"Meredith, I'm sor-"

"Can I get back to work now?" she asked, feeling a wave of overwhelming exhaustion suddenly slip over her, "I'll talk to you two later, okay? Just not when I'm dangerously close to murdering you."

"Is that a new sex game?" A voice called from the other side of the cafeteria, where a redhead bombshell stood with her arms crossed over her chest, wearing an expression or mild curiosity. She had already begun to make her way over to them, "The victim and the criminal… sounds kinky."

"Addison-"

"I'm not talking to you, Mark, I'm talking to my husband and his mistress. Can we have some privacy?" she snapped.

"No."

"Excuse me?"

"There's something you need to know."

"Do you really think now's the best time?" Derek muttered.

"No," Mark admitted while Addison's eyebrows creased deeper into her forehead, "But when else are we going to tell her? When Hannah's thirty?"

"Possibly," Derek said, before he decided to give up and let all hell break loose. After all, his marriage and affair had both gone up in flames within the last year; what more could he loose?
