AN: You guys are amazing with all the reviews. Thank you! Sadly, this is the last chapter of this story. I actually have 14 chapters of a sequel to it already written. I was going to keep continuing this story, but decided it would be better as a separate story. Be on the look out for that one in the next week or so.

By the time Lexie entered the apartment that night, Ella was asleep on the couch and Arizona had picked Sofia up an hour earlier. "Did she just fall asleep and you didn't have the heart to move her?"

"Yeah. I was going to move her before you got home, but you're home sooner than I thought you would be. I'll put her to bed and be right back," Mark said as he started to pick up the lanky girl after kissing his girlfriend. A few minutes later, he stuck his head in the master bedroom and found Lexie standing in front of the mirror.

"How'd it go with Addison this morning? I was expecting to hear from you earlier, but figured you were too busy with the girls to call."

"It went differently than I expected. She started by telling me that as soon as Ella is back in LA, they're packing their stuff. This caused me to freak and say that I will fight her for custody if I need to. I thought she was moving to New York again. Apparently she talked to Hunt and is moving back to Seattle. The hospital needs another OB and it would give Ella more time with me. They're moving back up here in about a month," he shared as Lexie made herself comfortable on the bed.

"Wow. That was not how I was expecting all of this to turn out."

Mark laid on the bed behind her and wrapped his arms around her. "I knew this was going to be a lot for you. I wanted to tell you sooner, but Addison asked that I not tell Ella. She wants to when she gets home next week. This is progress, though. You haven't stormed out on me, yet."

"I can handle this. I always knew that you came with Ella. Sofia and Sloan were different. I always knew about Ella, she wasn't a surprise to me. You know what this means?"

"What does this mean?"

Lexie took a deep breath and paused before continuing. "We're going to need a bigger place."

"We're fine here. Lots of kids have to share rooms, it's not like we're going to have both Ella and Sofia at the same time very often. I think this weekend went pretty well with both of them."

"Seeing you with both of them yesterday got me thinking about how much I love you when you're with your kids. It made me realize how much I want to have a baby with you. I was talking to Meredith about this during lunch today. She pointed out some stuff that I hadn't noticed. After lunch, I took a test that confirmed Mer's suspicions," Lexie paused again, waiting to see if Mark was following where she was going with all of this. "I'm pregnant, Mark."

Mark rolled over and laid quietly for a moment before saying anything, much like when Callie told him she was pregnant almost two years earlier. "You're right. We're going to need a bigger place. I know you said before that you weren't ready for a baby, but does this mean you're ready? I'll support you if you're not."

"That was almost four years ago that I said I wasn't ready for a baby with you. I'm older and I'm ready for this. The best I can figure, I'm about five weeks pregnant. We've got plenty of time to figure this all out. Just so you know, I'm freaking out right now."
