(Day 1)

Derek Morgan sighed as he looked at the clock. He should have been out of the office an hour ago, but since his best friend was sick, he was doing all of his own paperwork.

He, again, sighed before he turned his attention back to his paperwork.

It was going to be a long night.

Suddenly, a young woman appeared in black sweatpants, a white FBI t-shirt. She smiled, "Hi, I'm looking for da….David Rossi's office."

He got up from his from his desk. "Hi…" The world stumbled out of his mouth. "I'm Derek Morgan." He put of his hand, and shook hers. "His office is right up the stairs."

"Thanks." She headed up the stairs, and Derek watched her. Rossi answered the door, greeted the young woman with a hug and a rare big smile, and they both went into his office.

Derek sat his desk, forgetting about his paperwork, wondering who the woman was and how Rossi knew her.

He sat for another hour, getting lost in his own thought until a voice appeared behind him. "Morgan." The voice belonged to the Italian FBI Agent.

Derek turned around in his chair, and put on a smile. "Rossi."

"What are you still doing here?" He asked.

"Paperwork."

"Oh." Rossi smiled softly. "You should go home, Morgan. It's late." Derek nodded. "First, before you go, I would like you to meet our newest agent to the BAU. This is Isabell Rossi, my daughter."

She waved softly. "That is only if Aaron wants me on the team."

"Bambina, I'm sure he will." Rossi smiled to his daughter. "Morgan?" He asked grabbing the young man's attention back to him. "Can you sure her around while I finish up in my office, please?"

Derek shook his head, "Yes."

"Thank you." Rossi turned his attention back to his daughter. "I'll be done soon. Then we got to dinner."

"Okay, papa." She smiled.

Derek waited until Rossi left before, he spoke. "I'll show up the most important we have, it's where we hold the coffee."

She laughed, and Derek smiled. He loved her laugh. "Coffee is always a must working in the FBI."

"Yes." He nodded in agreement. He walked towards the newly built break room that was outside the loud crowded bull pen. "How long have you been with FBI?" He wanted to know more about the woman he stood by.

'Since I was 22 years old." She said proudly. "So, about eight years now."

Derek's eyes went big, he was impressed. "What department?"

"Quite a few." She smiled. "Kidnapping and negation for a few years. CAC for a year, and undercover for the rest. I love the undercover unit."

Derek looks at her a bit confused. "Then why do you want to switch?"

"Dad." She laughed, and butterflies in Derek's stomach grew. "Told me that Erin wants a new agent with your team and I was the first name on the list."

"Well, congrats Isabell."

'Not yet." She pointed out smiling. "Aaron has the final word. It is his choice."

Derek smiled back to her. "I'm sure he's going to want you. You have to much experience to pass up."

"Let's hope so." She said.

"Well," Derek stopped walking. "Here's the new break room."

"Comfy." She laughed.

"Isabell!" Derek heard Rossi call for her.

"That's my cue." She told him. "I'll see you tomorrow."

"Bye Isabell." He called after her.

"Bye Derek." She mocked back.

Derek watched her leave.

He has never met anyone like her. He wanted to get to know her. He hoped like Hotch would say yes to her joining the team.

He looked back to his paperwork, only for a second before gathering his stuff to go home. He couldn't focus on paperwork anymore. Isabell Rossi was stuck on his mind.
