A/N: Thanks again for the reviews! I'm glad you all like it! Now, I had to write some sadness. It needed more drama and I want it to tie closely to Lost, so I guess this had to happen. And I'm glad you all noticed pretty much all the characters popping up. More are coming into the storyline later.

Chapter 18: The End of the Innocence

Christian sat in his office thinking about Margo, Jack, Claire, and his soon to be born grandson. He was grateful for his family. He had just talked with a man who lost his only children in a car accident. Christian tried everything he could to help him. This was when being Chief of surgery hurt the most.

He had Jack and Claire's senior pictures now displayed. He loved talking about his two kids. That's when he found that old picture of Margo holding them as babies. Christian smiled thinking what his grandson would look like.

It was now March and in English, the students were working on their research papers. Suddenly, the intercom bell rang.

"Mrs. Hoying?" The main office secretary asked.

"Yes." The teacher answered back.

"Jack and Claire Shepherd are needed in the principal's office."

"OK. They're coming." Mrs. Hoying replied.

Jack and Claire were stunned. They never got called down. Kate and Charlie looked stunned too. The siblings got their things and left the classroom.

When they reached the office, the secretary said, "Mr. Locke can see you now."

"Thanks." Claire replied, but also worried from the look on the older woman's face.

They walked in and saw their mother talking with Mr. Locke. She seemed to be crying.

"Mommy?" Claire asked worried.

"I think you two should sit." Mr. Locke said kindly. They did and Jack looked at his mother worried too.

She tried to speak, but couldn't, so Locke did. "I'm sorry to have to tell you this, but it's such a shock." He looked at the two teens worried faces. "Your father just passed away."

Claire's eyes widened as shock came over her. She put a hand to her mouth and started to shake her head. "No! Not daddy!" Tears came as Margo rushed over.

The shock was still sinking in for Jack. "I don't understand. He was fine this morning." Tears were coming to his eyes as well.

Margo was finally able to speak. "It happened at the hospital. He had a massive heart attack."

Jack couldn't stop the tears from coming and he still was in disbelief. "I need to see for myself."

Claire just stared at her brother. "Why?"

Margo answered. "He needs it to know what happened. We are going straight to the hospital to talk with the doctors."

Claire still didn't understand but nodded.

"I'm so sorry for you loss. I not going to count the kids absent. I know what it's like to go through this." Mr. Locke stated.

"Thank you." Margo replied as the 3 of them left the school.

"I can't go in!" Claire screamed sobbing.

"We know. That's why you're staying with a nurse. You don't need anymore shock for the baby." Margo tried to warn her.

She nodded and Margo turned to her son. "Jack, you sure?"

He just looked at his mom with sad eyes. Dr. Bailey, Christian's replacement led them in.

"We just need to tell you what we found out. Chris had a very bad heart. He must have known about it and kept it a secret. He probably didn't want to hurt any of you. Margo, Jack, I'm so sorry for your loss." She said. "He was a great doctor."

"Does he look the same Miranda?" Margo asked.

She nodded. "He looks just as you remember him."

Margo and Jack went to Chris' body. Jack started crying. "He looks like he's asleep mom."

Margo was balling too. "I know. Just remember he's in a better place now."

"I'll try." He hugged his mom as they both cried. "You too."

The rest of the day was rough. Calls were made to Marty and her family, Margo's family, and friends. The news was a shock that no one saw coming. Kate and Sam rushed over when they found out. It hurt Kate so much to see her boyfriend, bestfriend, and a woman she looked up to like a mom hurt like this. Christian was like another father to her and she felt the great loss too. Sam helped Margo make the arrangements for the funeral while Kate tried to help Jack and Claire anyway she could.

The left as it got late and the remaining Shepherds tried to get some sleep. Margo had to take some medicine Miranda subscribed for her to help. Jack just lay in his bed thinking when a knock came to the door.

"Come in Claire." He could tell it was her. She opened the door and waddled in. She was 7 months pregnant now.

"I can't sleep." She said sadly as she sat down on the bed.

"Me either." Jack replied sitting up.

"Why did this happen?" Claire asked with tears in her eyes.

Jack stroked her hair. "I don't know."

"Daddy won't get to see my baby." Which he choose at that time to kick.

"He was excited to meet him." Jack smiled at the thought. It felt like the first time he smiled in years.

"I'm going to miss him so much." Claire hugged Jack.

"Me too."
