A/N: Thanks for the reviews for last chapter! It's always nice to hear that people are still interested in this story.

Teddy looked at Tom who was staring at Elizabeth. Nobody knew what to say. The uncomfortable silence filled the air until Allison cried out.

"I'll take her upstairs," Tom offered, looking for any way out of this. He went back upstairs.

Tom wasn't sure how to feel about seeing her. He hadn't seen her since their divorce was finalized. Seeing her brought up so many memories. Both the good ones of falling in love with her. Spending time with her and David for ten amazing years. And, the bad ones of them falling out of love after losing him.

Teddy found Tom lying down on the bed looking to be in thought. He had Allison lying next to him and she seemed much happier.

"Hey," Teddy said, trying not to startle him since he hadn't even noticed that she walked in.

"Hi."

Teddy sat down next to him with Allison in between them. "So, that's your ex-wife?"

"Yep," he answered. Teddy watched him. Usually he would be turning the uncomfortable situation into a joke. It almost scared her that he was speechless. "Can you please tell me what you are thinking about right now?"

Tom swallowed. "David."

Teddy nodded. "Yeah, um, I'm sure seeing her brought up a lot of memories."

Tom nodded. "Yeah, like when I walked in on her screwing another attending in an on call room."

"She cheated on you?" Teddy asked.

"When David died, it was hell. We just cope differently. I needed to be alone. She needed me to be with her. She took time off work. I spent more time at work. She found another man and I let her slip away."

Teddy was surprised that Tom had never told her about this. She figured that their divorce likely coincided with the death of their son. Many couples don't make it through that. But, Tom almost sounded...regretful. Teddy sighed.

"Sorry," Tom said sitting up. He could tell how that sounded to Teddy. He didn't want her to worry. "Seeing her today just was unexpected. That's all."

Teddy nodded. "Okay."

Teddy was surprised by his reaction to seeing his ex-wife again. Yes, it was surprising. But, she had made him completely shut down. Teddy didn't know whether that was because he hated her or loved her. Teddy sat with him in silence, trying to figure him out.

"I'm so sorry," Elizabeth said. "I didn't realize that Tom was who you were talking about this whole time."

"I mean, all this time that I've mentioned him you never thought to say that your ex-husband's name was Tom too?" Owen asked, feeling agitated.

Elizabeth sighed. "Tom is a pretty common name. I didn't think much of it."

Owen sighed. He wasn't sure what to say. He still liked her. Was it wrong for him to date Tom's ex-wife? They were divorced after all. Not to mention that Tom had slept with his ex-wife.

"I guess that Tom probably told you a lot of terrible things about me," she figured.

Owen shook his head. "Not really. Truthfully, he doesn't talk about you much."

"What about David?" she asked, tears coming to her eyes.

"Occasionally," Owen answered. It made more sense now. Why she loved kids but still didn't have any. Why she sometimes got teary eyed when Owen would talk about his kids. All because she had lost her child. "I'm sorry. I know this is probably strange for you. But, I hope this doesn't mean that we have to stop seeing each other."

"Owen, look, you're a great guy," she said. "But, I don't think there's a future here anymore. Seeing him just now, I couldn't help but think that maybe it was - I don't know - fate bringing us back together."

"You still love him? I thought you two got divorced because he wasn't there for you," Owen said.

"That was partially true. But, it's more complicated than that. I did wrong too. But, we were both hurting after David died. I never stopped loving him. It was just too painful for us to be together at the time."

Owen sighed. He couldn't believe this. Why did he and Tom have to have the exact same taste in women? "Well, he's engaged to Teddy."

Elizabeth laughed. "Yeah, but his eyes told me everything I needed to know. He still has feelings for me too."

Owen didn't know how to respond to that and just walked her to the door.

"Bye, Owen," she said. "I'm really sorry."

"Bye," Owen replied. He shut the door behind her. So much for thinking he'd found someone.

"Tom!" a voice called out as he walked into the hospital for his shift.

He turned around and saw Lizzie standing in front of him. "Lizzie. What are you doing here?"

"I-" she started. "I thought you should know that I ended things with Owen yesterday. I had no idea that you two knew each other."

"Um okay," he replied. "What are you doing back in Seattle?"

She was originally from Seattle but went to med school at Hopkins and lived in Maryland from then on.

"I moved back a while ago. I'm a professor at UW," she told him.

Tom smiled involuntarily. "You always said you wanted to teach one day."

"Look, I know you're busy. But, maybe we could grab lunch later and catch up," she suggested. She took a step closer to him and took his phone from his hand. She put her number in since it had changed since they last saw each other. "Just text me and let me know."

"Hey, did you like Owen's girlfriend?" Amelia asked Tom while they worked in the lab.

"Loved her actually," Tom joked. "For fifteen years."

"What?"

"He was dating Lizzie," Tom told her.

"Your ex-wife?" Amelia asked, shocked. "That must have been uncomfortable."

"Yeah," Tom agreed. There was a silence. "She wants to get lunch with me today."

Amelia raised her eyebrows at him. "Are you going to?"

"I mean, I'm curious. To know what she's been up to," Tom shrugged.

"Seriously?" Amelia asked.

"What?" Tom asked, defensively.

"Please don't make me say it," Amelia begged.

"Say what?"

"Not so long ago you confided in me that the biggest mistake you ever made was letting Lizzie walk away," Amelia reminded him, remembering when he had told her to fight Teddy for Owen when Teddy first came back to Seattle. "And, now you're going to have lunch with her? Tell me that you aren't trying to rekindle something."

"It's not like that," Tom insisted.

"Okay. Did you tell Teddy that she asked you to lunch?"

"Well, no," Tom admitted. "She wouldn't get it."

"She would think that there are still feelings there. And, the fact you didn't tell her shows that you have something to hide."

Tom sighed. "Well, I'm not going to make Teddy worry over nothing."

"So, you don't still have feelings for her?" Amelia asked, unconvinced.

Tom shrugged. "I mean, it's complicated. I never stopped loving the Lizzie I fell in love with. And, we both made mistakes leading to our divorce. She hurt me but I hurt her too. I'll always love her though. She was David's mom."

"Just be careful," Amelia warned. He could easily get himself into a lot of trouble with this.

"I was kind of surprised you said yes to this," Lizzie said as Tom sat down across from her.

"I felt like we had a lot to talk about," Tom replied.

"Me too."

"I'm sorry," Tom told her after a few minutes of silence. It was hard to even know where to begin. "After-after what happened, I handled things poorly. I couldn't bear going home. So, I worked. It was like I just had to keep my brain moving constantly or I would just- just die."

"I know," she said, a tear falling down her cheek. She wiped it away quickly. "I wanted to do that too. But, I couldn't. I needed you."

"I know."

"We sucked at communicating," she admitted. "I never told you that I needed you. I just expected you to know. And, I know better now. I know you were grieving too. But, it didn't feel like it."

"Trust me, I was," Tom assured her. "I should have fought harder for you. Especially when I felt you pulling away. It was just so much easier to let go."

Lizzie smiled. "It feels good to hear you say that. I messed up by cheating on you. But, you never were able to admit your faults in our marriage."

"I like to think I've grown a lot since then."

She smiled at him. Their waiter came over and gave them their food. Over lunch, they talked about good times. Although they still were hurting about David, it felt good for both of them to reminisce. They were the only people who would get it. Tom could never talk to Teddy about David quite like this. She couldn't contribute stories or fully understand what he meant when he talked about David's silly face, his imaginary friend, or his selfless nature. With Lizzie, she just understood.

"So, tell me about Teddy," Lizzie probed. "When's the wedding?"

"May," Tom told her. He shifted uncomfortably in his seat. He didn't want to talk to her about Teddy.

"How long ago did you two start dating?"

"Uh, about a year ago."

"Oh, so when she was pregnant with Allison?" Lizzie asked, with an amused smile.

"Yeah, why?"

"No reason," she said. Tom looked at her questioningly. "It just figures that you find someone who is having a baby to fall in love with. You've always been a sucker for kids."

Tom nodded. It was true. He liked most kids over most adults.

"So, is it just about the kid? Or do you love Teddy too?"

"I love Teddy," Tom said.

"I'm sure that she's thrilled that you're here," Lizzie teased.

"I haven't told her yet," Tom admitted.

"Why not?"

"I'm not sure," Tom told her. "I don't want to upset her."

"If we're just catching up, why would she be upset?" Lizzie questioned. Tom locked eyes with her.

"Tom," she said, putting her hand on top of his on the table. "I felt it as soon as I saw you again. That same feeling of butterflies that I had when you took me on our first date. We had something so special. And, we let it go way too soon. David would be so disappointed in us for letting ourselves lose each other."

Tom turned his hand over, lettings their fingers intertwine before pulling his hand away. "I'm not sure what to say."

"I didn't mean to throw this all at you," she said. "But, I still love you. And, I don't want to waste anymore time if you still love me too. Sure, we still have a lot to work on but I think we are both at a better place in our lives to try. We could still have a happy life together. Hell, we could have another baby. Start our own family rather than latching onto Teddy and Owen's. I'm not asking you to make a decision right this minute. But, I don't want to regret not telling you how I really feel. Again."

Tom smiled at her. He didn't respond. There was nothing to say. He didn't know how he felt. Everything she was saying made sense to him. There was no doubt in his mind that if David hadn't died that they would still be madly in love. But, they had let that tear them apart. But, they were older and wiser now. They could make this work. But what about Teddy? He loved her. He could see a future with her. But, Lizzie was his past and he still had feelings for her. He still regretted the way things ended. He still felt like he should have fought for her. And, he definitely considered the fact that David would have wanted his parents to be together. He had a decision to make and wasn't sure how he'd make it. Things with Lizzie could easily crash and burn. But, he had always felt regret for letting her go and this could be his chance to fix his mistakes. But, he would lose Teddy while trying to figure it out. Tom couldn't give her a definitive answer. He told her he'd think about it.

Teddy and Owen were cleaning up Allison after trying to get her to try all new foods for lunch. Neither of them had mentioned the uncomfortable encounter from last night yet. All Teddy could think about was how strange Tom had acted after seeing Lizzie. All Owen could think about was the fact that he had been so excited about his relationship with Elizabeth, all to have it fall apart in a second. At least this time, he didn't have to blame himself.

"So, about last night," Teddy said, wanting to talk to Owen about what would happen now. "Are you two still going to date?"

"No," Owen replied.

"Oh," Teddy said. She felt bad for Owen, knowing that he liked her. But, she was also glad that he wouldn't be bringing her around anymore. She wasn't sure if Tom could handle that. "I'm sorry. I know you really liked her."

"I just don't know how I'm supposed to date when Tom has been with every woman in Seattle," Owen complained.

Teddy glared at him. "That's not fair."

Owen sighed. "I know. I'm sorry. It's just annoying. I mean what are the odds that she is his ex-wife?"

Teddy pursed her lips, unsure if she wanted to know Owen's opinion on what she was going to ask. "Did Tom seem off to you?"

"Um, kind of, yeah," Owen admitted.

"You think he still has feelings for her?" Teddy asked.

"Of course not," Owen said, comforting Teddy. "Tom loves you."

Teddy smiled. Owen added, "But, she did say that she was interested in being with him again. So, just be careful."

"Well the road has to go both ways," Teddy said. "I'm not threatened by her."

Teddy wasn't sure how convinced she was of her last statement. The fact that she knew very little about Tom and Lizzie's relationship made her very nervous. But, Teddy knew that Tom loved her. They would be fine.

Teddy cuddled against Tom as soon as he laid down next to her in bed. She kissed him but could tell he wasn't fully there with her.

"You okay?" she asked, rubbing his arm.

He shook his head.

"What's going on?" Teddy asked sweetly. "You know you can talk to me, right?"

He smiled slightly at her. He wanted to tell her everything that was on his mind. But, it would only hurt her. He took her hand. "I had lunch with Lizzie today. I should have told you."

Teddy's eyes widened and she sat up in bed. "Um, okay. I wasn't expecting that."

"I know. I'm sorry," he said. "We had a lot to say to each other."

Teddy felt slightly worried. She trusted Tom completely but he hadn't told her about going to lunch in the first place and she didn't know why that was. But, had he told her from the start, she would have understood his desire to talk to her. They had had a child together. They had been through the worst thing that parents could imagine. Of course, he would want to know how she's doing now. "How do you feel now?"

"Confused," Tom admitted. "Please don't be mad. But, I still - I have feelings for her."

Teddy swallowed back tears. "What kind of feelings?"

"I don't know. I always regretted how things ended," Tom told Teddy. "There's a lot of history there and I can't help but wonder what would have happened if we had handled things differently."

Teddy bit her lip. She didn't enjoy hearing this. But, she wanted to know exactly how he was feeling. She didn't want him to sugar coat it. She forced herself not to cry. "Is that something that you want to find out? Do you want to try again with her?"

"I'm not sure," Tom wavered. "Part of me knows that I want to spend the rest of my life with you. But, part of me feels a little nostalgic and that I'd be doing a disservice to her, David, and myself if I didn't try to see how I really feel about her."

Teddy sighed and rubbed her hand down her face. This sucked, but she could understand his dilemma. Holding on to history rather than moving forward. Like all the time she spent pining over Owen instead of moving forward. Feeling the temptation of wanting to be with him even after he had hurt her so many times. Holding on too closely to a dream of what life could be like together without realizing that it wouldn't be anything like the dream.

She loved Tom. She trusted that he loved her too. She was sure that this was just a temporary set-back for them. And, if he didn't figure out for himself that Elizabeth was not who he was meant to be with, then he would always wonder. It would eat away at him, effectively ruining their relationship anyway.

"So, then, you go figure it out," Teddy found herself saying.

"What?" Tom asked, wondering if he had heard her correctly.

"I love you," she told him. She held back tears. "But, if you need some time to figure it out, then take it. I can wait."

"Really?" Tom asked. She nodded. He was amazed by how well she was taking this. He hugged her tightly. He thought for sure she would just end things when he said that he still had feelings for Lizzie. He felt so much better. Teddy hugged Tom back, wishing he would tell her that this was all some kind of joke.
