Danny had gotten a case where three teenage boys were killed behind a night club. When he and Jackie had found a witness who told them that a girl named Jessica Stephenson was the last one to see the boys alive Danny goes out and brings Jessica into the precinct to talk question her about what happened. Half way through someone came in "Danny you have a call from the commisoner" the detective said. Danny shook his head and told Jackie that he would be back as soon as he could. When Danny picked up the phone Frank who was sitting impatiently in his office for his oldest to pick up the phone. "Dad what is wrong I was in the middle of questioning a suspect?" Danny asked worried that Jamie, Erin, Linda, his grandfather, his two kids or nikki was hurt. "By any chance does the suspect have black hair, our color eyes, and remind you a lot of Joe?" Frank asked getting nervous all of a sudden.
He was shocked that his father could give a discription of the suspect from not even seeing her, "Yes, Dad how did you know that?" Danny said waiting for his dad to answer his question. "I know that because she is your youngest sister. She's Joe's faternal sister who went missing after Joe's death. We've been trying to find her since she ran off but no leads. Is her name Jessica Stephenson of the 86th precinct in Brookyln Joe's precinct before he died?" Frank asked having an idea that that answer would be yes. Danny was speechless not really able to speak for a few moments "I have another sister and you never told me about her!" Danny yelled not really meaning to but he had to get it out of the way. Meanwhile back in the interogation room.
Jessica who was still wearing her police uniform, slammed her hands on the table "I'm a respected cop out of the 86th precinct in Brooklyn and you suspect me to tell you where I was the night the three boys were killed. FINE! I was at my desk filing paper work away and five other cops could verify that to. Now i'm leaving" Jessica said before pushing the table closer to Jackie and shotting up and walking out of the room. Danny stopped her "Where are you going? We are not done yet now sit down!" Danny said sternly "Dad if you need come down here come down here now.
Frank hung up the phone and got a car to drive him to his son's precinct and fast. When Frank got there he saw Dannny and Jackie leaning against the wall watching Jessica making sure she doesn't go anywhere. Danny walked up to Frank "Jamie and Erin are on their way down right now they should be here in a few..." Danny didn't finish as Jamie and Erin walked in the door "What is it Danny all we got was that we were needed here as soon as we could?" Erin asked Jamie just nodded. Danny looked at Frank, "I'm sorry I didn't tell you guys this sooner but you have another sibling. Her name is Nicole Ann Reagan, she's Joe's faternal twin sister. She's been missing since Joe's death two years ago." Frank said walking over to Jessica who just looks up.
"What am I still doing here comissoner?" She asked. "Your here because we've been looking all over for you. My youngest daughter, I'm happy we finally found you after two long years." Frank said going in to hug Jessica but she then pulls away. "I don't know what your talking about comissoner I'm Jessica Stephenson not your daughter." Jessica said getting up but Danny pushes her back into the chair, feeling bad that he might be hurting his sister but he was trying to help his father help her remember who she was. "NIcole you have to listen to Frank I know you might not remember everything right now because your old baby sitters told you that you were adopted. You becoming a cop dissappointed them right?" Danny asked.
Jessica just looked at Danny confused at how he knew so much and then nodded "Yeah in fact they yelled at me and John hit me a few times when he found out." She said flinching as she remembered telling her dad. Danny punched the wall which was behind him now, he moved so that he could read Nicole's face, "Your biological father is Frank Reagan, you have two brother me Danny, Jamie who is standing a few feet to your left, Erin to your right is your older sister. Your a Reagan that why you became a cop." Danny said watching Nicole's face show some rememberence and smiled "Welcome back sis." Danny said hugging Nicole and then Jamie and Erin ran in hugging Nicole and welcoming her back as well.
