1She sat there staring at herself in the mirror. She was screwed how was she going to explain this one. She knew what she had done was wrong.

What did I do? I'm such an idiot. She thought to herself. She momentarily cradled her head in her hands before she stood up. She looked at the plastic stick on the counter, to double check. It was the same as it had been the previous 9 times it still had a little plus sign on it. She had realized something was wrong earlier when she realized she was late, but she figured that maybe she had hit the big 'm' word, she was getting to that age, but then the vomiting started. This was a good way to spend Christmas eve. Lindsey had gone to sleep and it was the perfect time to take the test. She was having trouble facing reality. She slept with a married man, they both new it was wrong, but they both knew what their feelings toward the other was... but the fact was he was still married. Catherine positioned herself on the edge of the tub again, and wept. The next thing she knew it was daylight. She wiped her mascara covered face, thrown the test in the trash can, outside so Lindsey wouldn't find out, and waited for her to wake up.

New Years Eve: The team had somehow managed to finish up all their cases, and decided to have a celebration.

"Hey Catherine you want something to drink?" Warrick asks as he starts pouring her champagne into the plastic cup.
"No, I'm fine, hey can I talk to you for a second?"
"About what?"
"A case, it will just take a second."
"Yeah sure."
Catherine silently drags him outside.
"Why are we outside?"
"I didn't want anyone to hear our conversation."
"Oh. I thought this was about a case."
"I lied."
"Are you ok you don't look so good." Warrick asks as he notices that all color has drained from Catherine's face. Before Catherine can reply she pukes in the bushes near the place she had been standing.
"So you're not ok."
"No Warrick I'm not."
"Tina said that flu season has been worse this year than any other she can remember."
"I don't have the flu Warrick. It's something a little bit more long term."
"Oh... I don't think I follow."
"This whole charade that you and I have going on is about to blow up in our faces." Catherine says as she begins to cry.
"Are you ok?"
"No, I'm not. I'm not ok with any of this. I'm not ok with the fact that you chose her over me when you barely knew her for ten seconds. I'm not ok with the fact that you cheated on your wife with me when the two of you shouldn't be married in the first place." Catherine bellows in anger with tears streaming down her face.
"Whoa slow down..."
"You know what forget it, I don't want to deal with this right now." Catherine says without breathing while still crying after cutting Warrick off.
"Why are you mad at me?"
"Why not? It's your fault that I feel this way." Catherine wails as she turns to walk to her car. Warrick gently grabs her arm.
"You can't drive not like this."
"LET ME GO. I'm not going to deal with this tonight ok? I've got to get home to my daughter."
"Ok." Warrick replies as he lets her walk away.

Warrick returns to the party.
"Hey where'd Catherine go?"
"She went home, she wanted to get home to Lindsey."

Warrick gives Catherine her space and tries to forget how angry she is at him.
