A/N: Thanks so much for all of the lovely reviews and thanks for reading! This chapter is slightly longer then the others, so enjoy!! By the way, the italics are flashbacks!

We ate in silence for a few minutes. "So you still didn't tell me why you were at the zoo that day," I said trying to break it.

He put down his fork, cleared his throat and took a sip of wine.

"I was there with my son," he said matter-of-factly.

I almost choked on a piece of my tortellini. "Your son?"

Chapter 4: Filling in the Gap

"Yes, my son. His name is Lucas and he is almost four years old," he explained not breaking my gaze.

I could not believe this. Chuck Bass has a son. A son. I never would have thought that I would ever hear those words come out of his mouth.

"Wow," I said finally. "You have a son, that's really great Chuck," I said a little too convincingly.

"What's wrong Blair?" he said noticing my discomfort.

"Nothing! I just…wow. I never thought I'd ever hear you say that. So, um… are you married?" I asked as I couldn't help but look down at his hand.

He chuckled a little and gave me one of his smirks. "No, I'm not married."

"Oh. Well me neither," I said quickly even though I knew he already knew this. Wow, could this dinner get any more awkward. "So who is the mother?"

Chuck took a breath before answering this question. "Her name was Heather. I met her about five years ago in France. We dated for a short while, but it didn't work out for us romantically. So we ended things, but a few months later I got a call from her telling me she was pregnant. We had only slept together once, so of course I wanted to be sure it was mine. It was, so I offered to help in any way I could. I knew we weren't going to work out relationship wise, but I figured we needed to be on good terms for the sake of our child," he explained.

As he was saying all of this I couldn't help but feel weird. These things he was saying were very un-Chuck. It seems like he has definitely grown up since the last time I saw him. I couldn't help but feel proud of all of the things he was doing.

"I bought Heather a new apartment," he continued, "and everything she needed for the baby's arrival. When Lucas was born, I helped out in every way I could. She would see him during the day, whereas the nights were mine. I would take him on weekends as well. It worked for a while."

"So, what happened?" I asked after he seemed to be finished with his story.

"Heather wasn't the best type of person. When I had met her, she was big into the partying, just like I was. Actually one of the reasons we broke up was because I was starting to get tired of the drinking every night. When the baby came around, she seemed to let go of that lifestyle too."

I looked at his face as he was saying this and I saw it turn to a sad and uneasy expression. He took another breath before continiuing.

"About a year ago, the maid that was working at the apartment called me and told me that Heather was acting strange. I told her to go home and that I was on my way to take care of it. When I got to the apartment, I found Lucas crying and screaming trying to get out of his crib. I picked him up to calm him down and went to find Heather. I found her passed out in the bathroom, vomit and prescription pills all over the floor."

I gasped. "Oh my god, Chuck. That's terrible. Is she alright?"

"She's fine. But after that I didn't trust her alone with Lucas. I gained sole custody of him and entered her into a recovery program. A few months ago, when I learned I'd be moving back to New York, I went to the program to see how she was doing, to see how we would work out the new development in my life. When I went to the center, they told me she had checked herself out, and had relapsed again. She left a note telling me to take care of Lucas because she knew she couldn't."

I didn't say anything. I didn't know what to say.

"So now, Luke and I are living here in New York, just us men," he said as he took another sip of wine.

"Chuck, that's awful. I am so sorry you and Lucafs had to go through that." I said as I reached my hand out to squeeze his on the table.

He held me hand for a few minutes before saying anything else. "Thank you Blair, but it wasn't your fault. It was mine for getting involved with someone like her. I'm just glad that I caught it before Lucas got hurt."

"Yes, you are very fortunate."

We sat in silence for a few more minutes just staring into each other's eyes.

"Well enough about me, what about you? Why isn't the wonderful Blair Waldorf married?" he asked.

There's a question. I thought.

"That's a very good question," I said chuckling a little. "I guess…well, after you and I ended things, I just focused on school. At the end of my sophomore year, I met a guy named Patrick. He was tall, dark, and handsome, just what I wanted. He was very nice to me and we started hanging out. Eventually we were dating. After about four months, I found out I was pregnant. He freaked out of course, we were only juniors at college. When I got that response out of him, I knew that I wanted nothing to do with him anymore. So I dropped out of school temporarily to focus on the baby. I moved back in with my mother. Serena was away at Brown, so I didn't really have anyone around to help me," I explained.

I looked up and saw Chuck wince a little. I wondered what he was thinking. I wondered if he was thinking what I was.

"Blair, I have to tell you something," Chuck said as he sat me down on the couch.

"What is it? What's wrong?" I asked, noticing the pain in his eyes.

"My father has asked me to move to France to run a new branch of Bass Industries. I leave next month."

I was speechless. The man I loved was leaving me. Again.

"No, Chuck. Don't do this to me. What about us? We only got back together last year," I said as tears formed in my eyes.

Chuck looked extremely hurt. "I know, Blair. Believe me, I know. You have no idea how much I wish I could stay here and be with you. But I can't. I can't let my father down. I just got his trust back, and if I lose it now, I'll never get it back."

I didn't say anything. I just sat there crying, trying so hard not to hear what I was hearing.

"We could stay together. We can do the long distance thing. I'll promise to visit as often as possible and you'll do the same."

I shook my head. "Chuck, I'm just about to finish my freshmen year at NYU, you'll be starting up a whole new branch for the company. You know that will never work. We'll end up resenting each other for making us stay together."

"Don't say that Blair, we can make it work," he pleaded.

"Chuck, I really don't think we can. I love you, Chuck Bass. But I think that we need to end this, for both of our sakes. You'll be starting a new life in France, one without me," I said still crying.

He looked into my eyes for what felt like an eternity. He didn't say anything, but I knew he realized that what I was saying was true. Staying together would only be a burden on both of us. "I love you too Blair. I always have, and I always will," he said putting his arm around me and letting my head fall into his chest.

We sat there for a long time, I cried into his chest and he tried his best to calm me down.

After a few hours, I decided it was time that I went back to my dorm. He nodded and walked me to the door.

"Blair," he whispered, not knowing what else to say.

I looked into his eyes, also filled with tears. "I know, Chuck. I know." And with that I walked out of his dorm. That was the last time I saw Chuck Bass.

"So once Amelia was born, I didn't really find time for dating. Amelia and I are perfectly happy right now, and we didn't need a man to get here," I finished.

Silence again. "Well you have done really well for yourself Blair," he said, finally breaking it.

"Yeah, you too Chuck," I smiled. I looked over at the man that I had once loved, and couldn't help but notice how much he had changed.

After we finished dinner, Chuck gave me a lift back to my hotel. He walked me up to the door.

"I'm really glad we did this Chuck, it was really good seeing you again," I said.

Chuck looked at me for a minute before saying anything. His gaze still burned me as it did when we were in high school. "What do you think would have happened…if I never left for France?" he asked hesitantly.

His question took me by surprise. As I stood and thought about it, I really didn't know. Would we have stayed together, and lived happily ever after?

"I don't know Chuck. That was a long time ago, I don't know what our lives would be," I answered.

He just kept his gaze on me. "I guess you're right. It was a long time ago. We were different people then."

"Yes, we were. I think we're still the same people, though. We've just…grown up a bit since then," I responded.

He chuckled a little. "Indeed we have."

More silence. This silence was killing me. How could we have nothing to say to each other? Or was it that we were just both so afraid to say what was really on our minds?

"So I would love to meet Amelia, and I'd love for you to meet Lucas," he said changing the subject from us to our little ones.

I smiled. "I would love that."

"Great," he smiled back. "I'll call you tomorrow to set something up," he said.

"Sure, sounds great." I replied.

We stood there awkwardly for another moment, both of us deciding how to say goodbye to each other.

Instinctively I stuck out my hand to shake his. "Well, thank you for dinner, Chuck. It was really good catching up," I said.

He looked down at my hand a smiled before reaching out to meet his with mine. He grabbed my hand and it immediately sent shivers down my spine. Some things never change. I thought. "You're welcome. I had a great time," he said before pulling my hand to pull me closer as he lightly brushed his lips past mine. "Good night," he breathed before turning around back down the hallway towards the elevator.

I stood in shock for a few moments. I reached up my hand to touch the lips that had just been once again kissed by Chuck Bass. It was barely a peck, but still, the sensation was still amazing.

No, no. Stop thinking like this. Yes, I was in love with him once, but it's been seven years. We've both changed. And so what if neither one of us is married. That doesn't mean anything. Chuck Bass was a love of my past. But the past doesn't matter anymore, does it?
