Author's Note: Okay, this is the last chapter. I'm kinda sad to see this story end because I was so attached to it for a while! lol. Thank you so much for reading this and for all the great reviews! And thank you again to Elphie Fae, who was a great beta! I love writing so I'm sure I'll write something again, as soon as I come up with an idea! Sorry the squee in this chapter is only implied; I need to learn how to write sex scenes! haha. Anyway, I hope you enjoy the last chapter and like the way this ended!

The next day Addison began taking her new medicine and tried to stay calm by reassuring herself that she'd be fine.

When she reached Mrs. Brennan's room she found the woman sitting up and holding her son. Bella was sitting on her lap and they were looking through a book. Both Rebecca and Bella were smiling.

Addison smiled too. She didn't want to disturb their family time so she decided to come back later to discharge them. As she walked away she thought about all they had been through in the past few months and how it might be hard for a while, but the three of them would eventually be okay.

The next few weeks went by fairly quickly. Addison was having fewer panic attacks and her nightmares were lessening as well. She managed to keep herself calm at work and if the topic of 9/11 was brought up somewhere else, she just tried to deal with each situation as it came. She didn't feel completely back to her old self, but she was getting there. She felt safe walking around Manhattan alone again, aided by presence of extra policemen in Penn Station and other important places. The people of the city were still patriotic and friendlier than they had been, but the air of fear was gone.

Two days after Christmas, Addison unlocked the door to the brownstone after a long shift and found Derek sitting on the couch, reading The Sun Also Rises and watching the 10 o'clock news.

"Hey Ad."

"Hey honey." She walked over and sat down on the couch next to him. He put the book down.

"Is this like the fifteenth time you've read that book?!" She smirked.

"No. It's only the seventh. And, for your information, I'm not reading it. I was just skimming through it to remember certain details."

He leaned over and kissed her. Then he put his arm around her and she leaned against him as they turned their attention to the TV.

The next news story started, "This is a video of the crowds this morning at the newly opened viewing dock over Ground Zero. The line began…"

"Sorry. I'll change the channel." Derek reached for the remote, but Addison grabbed his hand.

"It's okay. Leave it."

"Are you sure?"

"Yes." She settled back against him and they watched the rest of the story.

"You have off tomorrow morning, right?" she asked.

"Yea. I don't have to go in until 4."

"Good. I don't have anything until after lunch either."

"Oh, that's nice." Derek furrowed his brow, unsure of what she was trying to say.

"I want to go to the viewing deck tomorrow. Will you please come with me?"

"Why do you want to go there?"

"I have to, Derek. I need to go back there and confront my fears. I need closure."

He saw how determined she was and agreed to go with her.

"I'm scared Derek," she whispered.

"I know. Don't worry, I'll be right there with you."

She nodded.

He kissed her and pushed her back so she was lying flat on the couch and hovered over her, their lips still attached. He sat up and grinned.

"Derek," she said teasingly, "we're not even in the bedroom!"

He lifted her in the air as she squealed. "Ahh! Derek, put me down!"

He set her down on their bed.

"Now we're in the bedroom," he said suggestively.

The next morning they both got up and dressed at an earlier hour than they normally would on a day off. Both of them were fairly quiet that morning.

They took the subway downtown and Derek grasped Addison's hand during the entire ride. She just concentrated on breathing evenly and calmly.

When they neared Ground Zero they joined the line of people waiting to see the ruins and remains. Most people were quiet as they waited. Some were wiping tears or looking at photos they brought. Others were taking pictures.

When Addison and Derek reached the front they stepped on to the deck and peered through the glass. It looked like any other construction site, but felt different. It seemed as if there was a giant hole in the city, since it was surrounded by skyscrapers.

Addison leaned against the railing, staring at the place where the World Trade Center once stood. Tears formed in her eyes, but did not fall, as she thought of all her memories there and the tragedy that happened there just a few months earlier.

"You okay Addie?" Derek asked, walking over and putting his arm around her waist.

Addison wiped her eyes and turned to him.

"Yea, I'm okay. Let's go."

She took one last glance back at Ground Zero.

'I'm going to be fine,' she thought to herself and smiled, grabbing Derek's hand as they walked away.
