Hi! This is my first crossover fanfic. I know the first chapter is a little confusing, but I promise everything will make sense later. Please review!

Prologue
Jules/Kim's POV

Hi. My name is Juliana Callahan. Well, that's my name as of almost 15 years ago. My real name is Kimberly Hart. I am 33 years old, and I am an officer for the SRU - Strategic Response Unit - in Canada. My team is made up of Sargent Greg Parker, Team Leader Ed Lane, Officer Kevin "Wordy" Wordsworth, Officer Michelangelo "Spike" Scarlati, Officer Leah Kerns, and me. One member of our team, Officer Sam Braddock recently moved to the USA to help his sister raise his newly born nephew. We had been dating, but broke it off when he revealed to the team that he was no longer going to be living in Canada. It would have been too hard - long distance relationships never work. I know from experience. Anyways, my old life as Kim is way behind me.

Ch. 1
No one's POV

Team One was working out in the workout room until Winnie called them down to her desk.

"We have a hot call at the empty construction site on the corner of Woodman street and Cove street." She said.

"Why didn't you just tell us that over the earpiece? Why did we have to come down here?" Wordy asked.

"Because," Winnie started to explain, "I thought you might want to see and hear this first. The threat, name still unknown, is refusing to talk to anyone except for Jules."

Officer Callihan looked surprised. "What? Do you have security footage of the threat?"

Winnie nodded as Jules walked around the desk to see the computer. When the footage appeared on the screen, Jules' face turned white. The others noticed.

"Jules?" Ed asked. "Do you know him?"

Jules nodded and said, "I guess you could say that. Hey Winnie? Could you expand the picture so I can see the hostage?"

Spike picked up on what was happening. "You think you might know him or her, too?" He asked.

He got his answer when Juliana's face became even whiter. She walked back around the desk and stormed past her teammates.
"Jules, slow down! Who are they?" Leah asked.

Callahan turned around and said, "The threat, someone I never wanted to see again. The hostage, someone I thought I would never see again." And resumed walking.

Sarge sighed and said, "Jules, what's going on?"

She finally stopped walking and turned around. "It's a long story, which we don't have time for - and besides, these people are from... before I... knew you, Sarge." She said, trying to get a point across to her boss.

Sarge understood what Jules was saying. "You mean, that guy is..."

"Yes," Jules said

"And you mean that the other guy is your old..."

"Yes!" She exclaimed.

Sarge's eyes widened as he said, "Well, then we have to go!"

Jules sighed and said, "Finally!"

The rest of Team One followed in confusion.
