"What are you two talking about?" Olivia wonders.

"Several years ago, I found out," Casey begins. "It was after you had gone undercover as an inmate. It was a really tough case, for all of us. A few of us went for drinks," she stops abruptly.

"And?" Olivia raises an eyebrow.

"A few of us had too much to drink. We were trying to drink away the thoughts of the day, of that case," Casey admits.

"And, you saw Elliot leave with someone?" Olivia wonders.

Casey shakes her head, "He shared a cab with me."

"You two don't live anywhere near each other," Olivia points out.

"He wanted to make sure that I made it home, safely," Casey answers.

Olivia doesn't say anything. Casey freezes, afraid to continue.

"Tell her," Alex insists.

"You slept with him?" Olivia guesses.

Casey nods.

"Why are you telling me this? Do you think that it makes me feel better, because it doesn't. If you're trying to empathize, you have no idea what..." Olivia is cut off.

"I do know what you're going through," Casey tells her, reaching into her wallet. She pulls out a picture. She slides it across the table, to Olivia.

Olivia stares at the picture, blankly. She blinks, and then looks to Casey.

She shrugs, "I don't understand."

"Her name is Camille, she'll be four, in January," Casey replies.

Olivia says nothing. She re-examines the photo, of a little girl, with strawberry blonde hair, and big blue eyes.

"She's my daughter," Casey reveals.

"What?!" Olivia looks at Alexandra, "Did you know?"

Alex just nods.

"So, this is for real?" Olivia wonders.

Casey nods, "I don't tell anyone. I found out, after I was censured. I thought that I was better that way. I chose to teach, until I could come back, as an ADA. I got to spend a lot of time with her, the first couple of years, more than I do now."

"Why didn't you tell me?" Olivia questions.

"You didn't ask."

"Alex, you knew, too?" Olivia raises an eyebrow.

"Knew about, Camille?"

"About Elliot, and Casey?" Olivia clarifies.

"Not until she told me," Alexandra replies.

"It was just the once," Casey adds.

"With you," Alex responds, without thinking.

"What do you mean, with her?" Olivia inquires.

"I..." Alex grapples with the right response, "It was more than once. It was a handful of times."

"You said that your boss nearly caught you, one night," Casey points out.

"No," Alex shakes her head, "I got a call, from my boss, it wasn't as if someone walked in on us."

"Still you should have known better, than to do it, in your office," Casey censures her.

"I should have known better, period," Alex retorts.

"Wait, a minute. So, you are telling me, that Elliot had an affair with the both of you?"

"Yes," Casey confirms.

"Why to two of you?" Olivia wonders.

"It wasn't just the two of us. There was Dani, and at least a few others," Casey tells her.

"I never knew. He..."

"You feel as if he betrayed your trust, don't you?" Alex queries.

"Yeah," Olivia admits.

"So are you going to tell him?" Casey repeats her question.

"Did you?" Olivia responds.

"Yeah," she nods, "He sees her once a week."

Olivia looks at Alex, "Would you have told him?"

"No," Alex answers, too quickly.

"You seem very certain about that," Olivia notes.

"I wouldn't have told him. I don't think that I would tell anyone," Alexandra reveals.

"Does she have a child that she's failed to mention, too?" Olivia directs at Casey.

Casey shakes her head, "No."

Olivia looks at Alex, and then to Casey, "Are you sure, because he looks pretty damn, guilty."

"No, she doesn't," Casey answers.

Olivia looks at Alex. Alex says nothing. She wears a pained facial expression. She knows that Olivia will pick up on it.

"When?"

"When what?" Alex exhales, breaking eye contact.

"When did it happen?" Olivia queries.

"The end of two thousand and nine, into the beginning of two thousand and ten. Just after the new year, I broke it off," Alex explains.

"You went to another department, after that," Olivia points out.

Casey turns, to look at Alex. Alex refuses to meet either of their glances.

"Why did you leave SVU?" Casey begs the question.

"I told you," Alex reminds her.

"I know the reason that you told us," Olivia admits.

"It doesn't matter," Alex tries to brush it off.

"You were pregnant?" Casey takes over the questioning.

Alex nods, "It's why I chose to leave SVU. I didn't want to have to face Elliot. I felt guilty for what happened. I was afraid, that what I did would ruin his marriage. Things were awkward between us. I didn't even know what I was going to do, yet. I couldn't risk him finding out. He is not very open-minded. He has his beliefs. I didn't want to have my choices ripped away from me."

"You left SVU, so that you wouldn't feel pressured to make your decision?" Casey reiterates.

"I just wanted it to be mine to make."

"There is nothing wrong with that," Olivia empathizes.

"You know, it feels surreal, sometimes," Casey points out, "I wake up, on Sunday morning, with feet in my face. It's hard to believe that she's really mine. It's hard to think that her father, is someone who we all worked with, but knew so little about. He was good at keeping secrets. I guess, he never lets anyone in, completely."

"Alex, did you tell him?" Olivia tries to satisfy her curiosity.

"No. I never will, either."

"It's a moot point now, isn't it?" Casey asks.
