Author's note: This chapter will be done to a song title prompt. The first chapter was the prologue and was just to let you all see how Emily and Aaron first met. This second chapter picks up where Emily and Aaron end up meeting up once again as she joins the BAU. For all of you out there who love Hailey I'm sorry to say that when Emily joins the BAU Aaron and Hailey are already separated. Emily is 36 and Hotch just turned 41. Also please remember I said this would be AU so yes Aaron is nice when he sees Emily and finds out she is joining the team.

Song Title Prompt: I'll Be There for You by Bon Jovi

Emily Prentiss was nervous about today. Today was the day that she would be seeing the man who stole her heart for the first time in seventeen years. She did try to call him one about fifteen years ago but his wife answered. She left her name and number for Aaron to call her back but he never did. She wasn't sure if that was because he didn't want too or because his wife never gave him the message.

Her daughters' were ready to go to school. They knew that their mom was worried about today but they also knew that today would turn out alright. They hoped that they would finally get to meet their father. Their mother has told them all about him and they loved him even though they have never met him. They just hoped that he would love them too.

"Mom quit stalling. You look terrific. Now let's go and Ashleigh and I will come to your work when we're out of school." Ashland said.

Emily groaned but quit doing what she was doing. "Alright then let's go. Make sure you tell them at the front desk who you are. I will leave instructions with them and your names."

Both Ashland and Ashleigh nodded and pulled their mom out of their house. They got in their car and Emily got in hers. The girls' waited to make sure that their mom left before pulling out of the driveway. They headed to school with their minds on their mom. They both hoped that she would get through today in one piece.

Emily pulled into the parking garage of the FBI Headquarters and took in a couple deep breaths before she exited her car. She knew that Aaron knew she was coming because she talked to someone with the name of Jason Gideon yesterday. He had called to tell her that he would like to see her before the briefing. Once she did her breathing technique she exited her car and headed towards the elevator. Once on the elevator she did the breathing technique again until the elevator stopped at the floor she needed. She exited it with a forced smile on her face. She couldn't believe that she was so nervous.

Aaron Hotchner knew that he was getting a new team member today and he knew who it was. His heart was beating in his chest hard and fast. It had been seventeen years since he has seen her. He still remembered the sound of her voice. He still remembered the color of her eyes and the way she lit up when she smiled. He had tried to find her after she left but he didn't succeed. It was like she fell off the face of the earth.

He looked up when he heard someone whistle. His heart just about beat out of his chest when he saw Emily walking in. She was still as beautiful now as she was back then. He walked to the middle of the bullpen to meet her.

"Emily." Aaron said softly.

Emily looked up as she heard the voice she heard every night in her dreams. "Aaron."

Aaron let the smile show on his face when she looked up at him. "It's been a long time Emily."

Emily blushed but nodded. "Yes, it has been. Do you want to have this conversation here or shall we go up to your office?"

Aaron looked around and saw that Gideon, Morgan and Reid were all staring at him and Emily with curiosity on their faces. "Let's go to my office Sweetheart."

Emily's breath stuttered to a stop when she heard Aaron call her Sweetheart. She nodded and waited on him to lead the way. She was surprised though when she felt his arm go around her shoulder and guided her to his office.

Once they were in his office Aaron shut his office door. What he did next surprised him and Emily. He pulled her into his arms and swooped down catching her mouth in a blistering kiss. He only pulled away from the kiss when they both needed to breathe.

"I have been wanting to do that for the past seventeen years." Aaron said.

Emily stared at him wide eyed. "You have?"

Aaron nodded his head and led Emily to the couch and sat her down before sitting next to her and turning to face her. "Yes, Emily I have. I tried looking for you but it was like you fell off the face of the earth. Seventeen years ago I wanted you. That hasn't stopped at all even when I tried to stop it. I went back to Hailey but I wasn't in love with her. We had a kid two years ago and I'm now separated from her for good. I have been for a year. I walked in on her cheating on me again. The real sad thing is that our son was in the next room awake and crying and she ignored him. I have full custody of him."

Emily's eyes went hard when she heard about how his wife or ex wife treated him and his son. "I tried to call you about sixteen years ago and your wife answered. I left my name and number with her. She said that she would give you the message. I waited a month before I gave up any hope I had when you didn't call me back."

Aaron's eyes went wide and then hard. "She never gave me any message from you. If she would have I would have called you back. I swear Emily I would have. I loved you then and I still love you after all these years apart."

Emily licked her lips and sighed as she got the courage to tell him what he needed to know. "Aaron you have two daughters'. Their names are Ashleigh and Ashland. They will be coming here to meet you after they get out of school."

Aaron's mouth dropped open and a smile spread across his face. "I'm sure I'll love them Sweetheart. I know I wasn't there for you back then but I'll be there for you now if you will let me."

Emily smiled. "I would like that Aaron but I want to take it slow. Last time everything happened so fast that this time I want time to savor it all."

Aaron nodded and then kissed Emily tenderly before standing up. "I should introduce you into the rest of the team."

Emily smiled. "I would like that. They are probably wondering what in the world is going on."

Aaron let out a slight chuckle. "That they will. They have probably already called the other women up. Be prepared for questions."

Emily shook her head and laughed. "Oh I will be. After all remember who my mother is."

Aaron nodded. "How is your Mother doing?"

Emily scowled. "Honestly I don't know and I'm not sure I care. I haven't seen much of her in the past seventeen years. She still blames me for my brother's death."

Aaron's mouth went into a straight line and he pulled Emily into a hug. "Sweetheart it wasn't your fault."

Emily smiled as she looked up into Aaron's eyes. "I know it wasn't Aaron. Now take me and introduce me into the other members of your team."

Aaron nodded and opened his office door and pulled Emily out of his office. He looked down into the bullpen and saw that the men had indeed called the women to come into the bullpen. He shook his head and chuckled as he thought about how predictable they could be.
