Jamie Reagan and his partner Eddie Janko had just gotten off tour. They had worked a 5 a.m.-2 p.m. and were about to head out for lunch when something stopped them.

"Reagan! Janko! My office NOW!" Sargent Renzulli yelled at them. The partners gave each other a worried look, not sure what they had done. Reluctantly, they headed over to their boss's office.

"Hey Sarg, what'd we do this time?" Jamie joked as he walked into the small room.

"Nothin'. We have an opportunity for the two of you though. Usually I think the two of you are crazy for not accepting your feelings, but today I'm grateful." Renzulli explained.

"We?" Eddie asked as she looked around confused. Finally, she spotted her partners brother in the corner waving with a smile on his face.

"Oh. Danny. What are you doing here?" She asked, still confused.

"Well, like Sargent Renzulli said, we have an opportunity for you two love birds. Baez and I have been dealing with a case where some psychopath has been killing newly married couples. They have a type though; not just any type, but a type that seems to fit you two well. So, Baez and I were wondering who we knew who had enough experience and was realistic enough to pull it off. We instantly thought of you two. You in or not? I mean, you two are practically married anyway. What would some undercover work hurt?" Danny explained with a smirk. The partners didn't need to think twice. One look at each other, and they had made their decision.

"We'll do it!" They exclaimed in unison.
