Alex was sitting on her couch, now drinking tea instead of coffee. She knew that she shouldn't have called in sick, but she couldn't bear to face Allison. Alex was the kind of person who hated confrontations, that's why she ran away to Germany. Coming back to New Jersey was the biggest mistake of my life. Well, second biggest. Maybe I should just leave again. Allison obviously started her life over, and I came back here and ruined it. Alex leaned back into her seat and fiddled with one of the many holes in her couch. All she needed was someone to talk to. Anyone. Her mind flew to the friends that she had before she went Germany. Once she moved countries though, she lost touch with all of them, and now she had the same problem with the friends she made in Germany.

Sighing, Alex looked back down at the couch and was startled to see that she pulled a lot of stuffing out. Getting up Alex stumbled into her kitchen and refilled her mug with more tea. Taking a sip Alex made a face, and spat the tea back into the mug. It was cold; her kettle must have stopped again. Heaving another heavy sigh, Alex decided to take a walk, to go anywhere just to get out of her apartment.

Grabbing her coat, Alex stepped out her door. After the usual struggle of locking the door (The lock was a little loose,) Alex quickly rushed out of her building to the outdoors. Taking a deep breath, she quickly relaxed; she was always one for being outside. Hesitating where to go, Alex let her feet carry her where they wished.

Losing herself in her thoughts, Alex thought of all the people she missed, who used to live here. Maybe she could call them up and see how they're doing, or see if the even remember her. Still allowing her feet to trace familiar paths, Alex eventually took her coat off, wondering why she took it in the first place. Becoming almost carefree, Alex looked around to see where she was. When she recognized her location her breath was sucked right out of her. She was standing at the intersection of 15th Avenue and 32nd Street.

She didn't even notice right away. It changed a lot since she been here last. Looking around she saw shops, and stores everywhere. Before she left for Germany, this intersection wasn't even industrialized, there weren't even lampposts. This is the spot that changed her life.

AN: This is how the next little bit works: everything in normal writing is Allison talking to House, everything in italics, is Alexandra's flashback.

"Matt and I had gotten married. We were going to leave for our honeymoon the next day, and Alex and Matt went out for a drive. I suppose they got sidetracked…"

"Hey, Alex, pull over here," Matt said looking out the window. Alex obediently pulled the car over and saw what Matt was looking at.

"A club?" Alex questioned as he started to get out of the car.

Matt glanced back at her and grinned, "I told a couple of my buddies that I would meet them here. Just for a little bit, we'll get out of there soon, I promise."

"I can't believe you used me as a taxi," Alexandra scoffed jokingly, but followed him anyways. When they opened the door, they almost got blasted away by the music. "Where are they?" Alex called out to Matt, squeezing in the overcrowded room.

"They should be around here somewhere…I'll find them and get back to you soon as I can," Matt yelled back, and before she could answer he disappeared into the crowd. Sighing, Alex wedged through the throng and finally arrived at the bar. Not knowing if Matt was going to have a drink or not, she ordered a glass of water. To help herself pass the time, she decided to start a friendly conversation with the guy next to her. Before she knew it, she was laughing along and having a great time. Then she looked at her watch.

"Oh my gosh. Have I really been here for an hour?" she glanced at Jack, the guy she was chatting with. "Sorry, I have to go. Nice talking to you." Alex quickly jumped out of her seat and hurried around, searching for Matt.

"I was waiting for them, and Alex called my cell phone, which was in the car. Alex left me a message."

"Hi, Allison? It's me, Alex. I know I said we'd be back by now; we'll try to be home as soon as possible. Sorry, see you soon. Bye," Alex yelled into the phone, then continued looking for her brother-in-law. She finally saw him, and called out, "Hey, Matt! Do you have any idea what time it is? Your wife is at home waiting for us!" she hollered over the noise, but once she got closer she stopped short. Matt was obviously drunk. Fuming at the sudden turn of events, Alex marched over to him. "We have to go," she said, while forcefully grabbing his arm. She glared at a couple of his friends.

"What? We had to have one last party together before he left for his honeymoon," on guy tried to rationally explain.

"Whatever," she mumbled, half dragging and half leading Matt to the exit. Once she reached the outside, Alex inhaled deeply. She tried to remember where she parked, as Matt started babbling in her ear.

"Wasn't that fun?" he asked, slurring his words.

Alex answered coldly, "Have fun explaining to your wife, why you had to go and get drunk, when tomorrow you're leaving for your honeymoon."

"Awww, are you mad at me?"

"You think? Of course I am. I told Allie we'd be home 45 minutes ago. It's just like her to be worried sick by now. I see the car, come on." Alex started to walk briskly to the car, Matt stumbling behind her.

"Alex, I'm driving, okay?" Matt stated.

Alex snorted. "The hell you are. Sit in the passenger seat," she commanded. Matt did as he was told with a lot of mumbling and sighing. Alex sat behind the wheel.

"Hey let's sing, Allie."

Alex sighed, "I'm Alexandra, not Allison."

Matt squinted at her, then gave her a lopsided grin, "I knew that."

Rolling her eyes, Alex backed up the car. "Just sit there, and shut up. Don't you dare start singing."

Matt ignored her and started to sing, very off tune, some old Back Street Boys song. Alex winced but kept on driving, trying to pay as much attention to the road as she could, it had gotten dark. Alex turned onto a street and sighed. She hated driving down 15th Avenue when it was dark, you couldn't see anything.

"I don't know what she was doing, but she wasn't paying any attention on the road."

Alex looked over at Matt, and saw to her horror; he was trying to light a cigarette. "Matt! You just quit a few months ago-" Alex cut herself off, realizing she was trying to explain something to a drunk person.

"Come on, Allison, just this one."

Alex decided not to remind him again, that she was not Allison. "Give me the cigarette."

"No."

"Give it to me!" Alex tried to snatch the cigarette away from him.

"Allison, look out!" Matt yelled, his hand on the dashboard. Alex looked up, and saw two headlights coming right at them. All she had time to do, was scream.

"A semi truck hit them, Matt died on impact."

Allison finished her tale and was surprised to find that her checks were wet. She glanced up at House, who was studying her silently. Finally he slowly walked up beside her.

"I'm sorry," he paused while she nodded, then continued. "Why did you tell me that he died of thyroid caner?"

Allison met his stare until she was forced to look away by the intensity of his gaze. "I don't know. At the time I didn't know that that part of my life would come here."

House accepted this comment without question. "We have no cases right now, take the day off," House said quietly, and before Allison could respond, he turned around and hobbled to his office. Allison stood by herself, stunned at House's understanding. Taking a deep breath, she decided it was time to talk to her sister.

Alex was back in her apartment, trying to concentrate on a book. Molly turned and yelled to Pete, but he already took snatched the... Alex found her thoughts wondering again. Giving up on the book as a bad job, she stood up and decided to get something to eat. This time being smart enough to leave her jacket at home, Alex opened her apartment door and was startled to come face to face with Allison, who had her hand raised as if to knock on the door. Her first reaction was surprise, but it quickly turned to tiredness. She didn't have it in her to argue, fight, or even talk to Allison. Alex looked at her sister wearily, waiting to hear her say whatever it was she wanted to.

Allison stared back at her sister, feeling (as she always did,) like she was staring in a mirror. She opened her mouth to say the speech she was practicing in her head, which was full of forgiveness and understanding, but something held her back. It was one thing to forgive someone in thought, but to do it in person was harder. Seeing her sister brought all the anger and rage she was harbouring these seven years. Allison could forgive her twin, and move past the sorrow that should have ended a long time ago. Or she could continue to hate and hurt at the same time. To forgive her sister would be wonderful, to finally let go, would be a blessing. The easier option was to carry on the path of destruction and pain she was on, which would be more satisfying then saying three simple words. Allison had a choice, and was clueless as to which she would decide.

Matt. Just thinking his name gave Allison strength, and forgetting the speech she well prepared, she made eye contact with Alexandra and took a breath.

"I forgive you."

THE END
