Alexandra Cabot stormed into the squad room, dirty, disheveled, and determined. She had the look of a woman on a mission.

"Hey, Alex." Elliot said casually, forgetting for a moment that Cabot was supposedly dead.

"Alex!" Munch yelped. "But, but...you're dead!" He cast an accusatory gaze at Elliot. "At least, that's what some of us thought."

"Oops," said Elliot, stuffing his face with a Krispy Kreme. "Did I forget to mention that she's actually alive and in the Witness Protection Program?"

"Not anymore," Alex said with grim satisfaction. "I got tired of waiting for the feds to do anything." The detectives all nodded. Never leave up to the feds what you could do yourself. "So I tracked Valez down myself and killed him with my bare hands. And let me assure you, he's singing in the soprano section of the heavenly choir. Where's Olivia?"

"Dunno," Elliot shrugged. "We haven't seen her all day. Why?"

Because I'm unbelievably horny after three months on the lam and need to get laid NOW. "Oh, I just wanted to say hi, I'm not dead, stuff like that."

Cragen wandered out of his office. "Alex, thank god you're here."

"Am I the ONLY ONE who's surprised to find out that Miss Cabot is, in fact, NOT DEAD?" Munch howled. "That her supposed death was part of a huge GOVERNMENT CONSPIRACY..."

"Can it, John." Cragen said, irritated. "Alex, here's the deal: Our new ADA seems to have gone missing. We're in deep trouble on this case. Can you lend us a hand?"

"Casey's missing?" Elliot snorted. "Have you checked the batting cages? Maybe she just lost track of time."

"Maybe she's getting her hair styled," Munch said, forgetting his indignation in the face of a prime Casey-bashing opportunity. "No wait, she clearly only spends about 30 seconds on that."

"Maybe she went back to law school," interjected Fin, arriving with the coffee.

"Going "back" would imply that she'd ever been in the first place."

"Okay, enough," said Cragen. "Yes, we all know that Casey is woefully inadequate, but it doesn't matter because Miss Cabot is here to help us out. Right, Alex?"

Alex sighed. What the hell. I've waited this long... "Okay Captain. What do you need me to do?"

"Elliot's about to interview a suspect. I need you to supervise him. The rest of us will make ourselves conveniently scarce."
