"Can I suspend the Hippocratic oath so I can kill a patient?" Izzie forcefully slammed her lunch tray down on the cafeteria table and sat down.

"Having a good day so far Barbie?" A tired Cristina toyed with her salad.

"Shut up Cristina!"

"Oooh, Barbie is pissed. I'm scared."

Alex grabbed the seat next to Izzie, trying to ignore her shifting away from him.

"What's wrong Iz?" Alex grabbed a french fry off her plate.

Shooting Alex a dirty look, Izzie addressed Cristina. "If I hear the name 'Bethany Whisper' one more time, I'm going to grab a ten blade and start swinging!"

George and Callie take the last seats at the table. "Who's Bethany Whisper?" Callie looked from Izzie to George, who tried to warn Callie with an urgent shake of his head not to pursue the topic.

Izzie retrieved a crumbled piece of paper out of her pocket and tosses it at Callie, who deftly captures it with one hand.

"Impressive," Alex nods at Callie, his mouth full of tuna fish.

Callie unravels the wad of paper. It was a page torn from a magazine, an advertisement for women's lingerie. Callie stares at the woman depicted in the ad, glances at Izzie before returning her attention to the ad.

Cristina shrugged. "I told Izzie that if I were her, I'd walk around naked all the time."

Izzie silently warns Alex not to say a word. Alex smirks, "Too easy."

Izzie reaches across and snatches the offensive piece of paper from Callie's hands, shoving it back into her pocket. "Someone left an old magazine in a patient's room. The guy kept grabbing my shirt as I checked his stats and asking what I had on underneath it."

"So," Cristina interrupts. "What happened with Shepard after I left last night?"

George snorted milk through his nostrils. "Dr. Shepard? Last night? Where did you see him?"

"George, you have milk dripping from your nose," Cristina looked at George in disgust as Callie hands him a napkin. "He came past Meredith's."

"God, I hope he didn't drive," Callie gasped. "He looked pretty bad when we saw him."

"When did you see him?" Alex is curious.

"In Joe's parking lot. He was holding onto a car trying not to fall over."

"I must have missed you two by seconds," Cristina grinned. "He and I had a little heart-to-heart in the parking lot after we saw him in Joe's with some bar skank."

"Joe told us about that," Callie nodded as George choked on his milk. "Grey was all over him."

"Meredith wasn't with Derek at Joe's last night." Izzie corrected Callie. "She was with us. We all saw him with the skank."

"What is it with you and that milk Bambi?" Cristina grumbled.

Callie thumped George on the back. "I think he's trying to say that skank has a name."

"How would Bambi know the name of a skank?" Alex chuckled. "Especially that one?"

"Because she works here," George wheezed. "Dr. Lexie Grey."

"George, Lexie Grey is the name of Meredith's half-sister." Izzie stated. Cristina, for once, was at a loss of words.

"That's the name she gave before I pulled the barstool out from under her." Callie opened her container of yogurt.

Cristina was impressed. "Nice. Just when I think you're a boring married lady, you rise."

George looked at Callie as if she had sprouted a second head. "You did what?"

"Please George. That girl wasn't listening to a word you said. So I provided a little reinforcement."

"You pulled the barstool out from under her?" George repeated.

A beeping noise had everyone grabbing for their pagers.

"Having trouble understanding English O'Malley?" Alex looked at his pager. "Guess it's me. Oh Yang, Mer wants you to meet her at Joe's tonight." He grabbed his tray and left the table. Izzie watched as Alex disposed of his trash and stopped past a table of nurses. Olivia had waved him over. After a few words, Alex left the cafeteria.

"That's kind of harsh Callie," Izzie remarked, her gaze resting on the nurses' table. "Did you stop to think that she may not have realized Derek wasn't available?"

"Please Stevens. From the way she was going on about Derek's hair, that never crossed her mind. And George, in his gentle way, tried to explain the facts of Seattle Grace life to young Dr. Grey." Callie leaned forward. "Nothing was registering."

"What is your problem, Izzie? Are you defending her?" Cristina frowned.

"No, I'm not defending her. I just think dumping a drunken, clueless female on the ground is a little excessive." Izzie toyed with a cold French fry. "Besides, we have a bigger problem."

"What?" George was confused. The three women shared a look.

"Meredith's half sister," Callie brushed an imaginary speck off of George's shoulder. "Is interested in Meredith's boyfriend." Callie looked Izzie. "Is Shepard still Meredith's boyfriend?"

Izzie nodded.

"Figures," Cristina threw her fork onto the tray. "Besides, there's an even bigger problem."

Izzie, Callie and George looked to Cristina for guidance.

"People, why do I need to remind you that Meredith has no idea her dear, darling, apple-of-her-father's eye half sister is now employed here?"
