"Excuse me," you ask the front desk sergeant as you and your partner enter District 21, "I'm looking for Detective Halstead."

The front desk sergeant, and older woman with grey hair looked you and Lasalle up and down. "It's not Boy or Girl Scout season, so what the hell do you want?"

Chris rolled his eyes and pulled out his ID. "Federal agents. We're here to see her brother about a case."

The desk sergeant's eyes grew wide. "You're Jay's federal agent sister?"

You nodded. "Yes ma'am. I've got plenty of tea to spill if you want to know anything while I'm here."

The sergeant laughed coming out from behind the desk and extended her hand. "Sergeant Trudy Platt. Jay has told me a lot about you."

At that moment, Jay came through the screened in door. He smiled when he saw you and gave you a big hug.

"Next time don't wait so long to come home."

You laughed, "Hey, y'all are welcome down in New Orleans anytime. How's Will doing?"

"Good. He's excited to see you."

"Well he better be. Especially when I bring home some good southern cooking."

Jay shook his head and laughed. "You've been down there for too long."

Lasalle smirked. "Nah, she just likes our culture too much. Plus we have a great night life, food, and hospitality."

You nodded with a grin on your face. "And some of the best bars in the country."

Jay shook his head. "That's it. You're coming to Molly's after work for drinks. Both of you."

"Now that sounds like a good idea. I like your brother already, Hal."

"Oh yeah, Jay this is Special Agent Chris Lasalle, my partner and one of the best NCIS agents. Chris, this is my older by four minutes twin brother, Jay."

Both of the men shook hands and Jay led you both upstairs to the squad room.

oOo

After the introductions were made around the room, both you and Lasalle had the attention of the Intelligence Unit.

"A few months ago, our team based in DC, investigated a plane crash with naval personnel on it," Lasalle started.

Ruzek raised his hand a little. "I'm not sure I understand. What's the US Navy got to do with a plane crash?"

You cocked an eyebrow at him. "Because there was a naval officer aboard the plane, and we investigate any type of crime involving the US Navy or US Marines."

Ruzek nodded for you and Lasalle to continue. "On the manifest, it listed the sibling of one of our forensics scientist, who didn't board the plane at all," you continued.

"Fast forward just a few days into the investigation, and our team found out that the project, which y'all found missing components from, was created by this man, Jenner Blythe."

"His company wanted to help the Navy with developing an undetectable ship," Lasalle took over. "We were able to prove that Blythe stole his own designs after blaming some Russian operatives down in New Orleans, but the project went missing."

"That is," you paused and looked around the room, making eye contact with your twin, "until you called me."

Voight followed your gaze before nodding. "Okay. How do you want to do this then?"
