Jack knew what she was doing the minute he walked into her office and saw her there. He knew what she was doing. He knew why she wore the black leather pencil skirt with a low cut red blouse and red heels. He also knew the necklace that fell right at her cleavage was intentional.

The last time she'd visited his office she wore the same skirt. He'd been stressed over a complicated surgery and barely sleeping. She brought him lunch, which he didn't eat. When he ignored her, she leaned back on the leather sofa as she hiked her skirt up. By the time he glanced up, he had a full view of her exposed intimacy. After getting his attention, she knelt down in front of him, sucking every morsel of tension away.

"I've been calling," he said softly. He felt like he was around a feral animal; he was afraid any sudden movement or loud noise would spook her.

"Trust me, I know."

"Kate, you've got to believe me…"

"There's nothing to believe. It happened. You left me."

Jack sat next to her on the couch, so close he could see each and every freckle. "You came here to talk, let's talk. Please."

"I came here because of Aaron."

"I've tried—"

"I know. I was wrong to stop you from seeing him. I'm sorry," she whispered. "I won't stop you from seeing my son." She stood up, ready to make a quick escape.

"He's our son. You know we both share the same connection to him."

Kate sighed. He was right; he was just as much Aaron's father as she was his mother. She had no more right to him than Jack.

Jack didn't stop, he stepped closer, making Kate back up until her back was against the wall. "Why'd you want to come here? Because it reminded you of when we had sex here?"

"Even if I had invited you to lunch, we've had sex in just about every restaurant," she whispered to emphasize her point.

"You wore that outfit…"

"Because I want you to suffer," she said, her voice a low growl. Her eyes darkened as she glared at Jack. "I want you to feel as awful as you made me feel. I'm going to make this as hard—"

He grabbed her by the ass and pulled her so close that she felt his hardness press into her thigh. She bit her lip, stifling a moan.

Jack knew he had her. He had no intention of ever giving up on her so he was fine with cat and mouse games.

"When are you coming to see Aaron?"

"Not just Aaron."

"When are you coming to see Aaron?" She repeated, emphasizing their son's name.

"He's too young to understand this. You know he is. I understand that you don't want me in the house right now, Kate. I know I messed up. I genuinely didn't know you were in Hawaii. But don't punish Aaron for this. At least give me family time when I come."

He could see the internal debate written all over Kate's face. More than that, he saw the pain. The pain that he caused. Pain that he didn't know how to fix. He had abandoned her and triggered all the memories she tried to push down.

"Thank you, by the way."

"For what?" She asked, snapping back to reality.

"You could have ran but you chose to come home. You came back."

"I was going to take Aaron to the park later if—"

"Of course! I'd love to!" Jack yelled.

At the park, Jack stayed on the playground with Aaron the majority of the time. Kate had expected Jack to sit by her and try to get into her good graces. Still, she wasn't surprised to see Jack completely devoted to Aaron.

As a result, Aaron slept the entire way home. Jack decided now was the best time to talk to her and also time to fill the awkward silence.

"I was wrong, Kate."

"You al—"

"No, before that. On the beach…"

"Jack," her voice shook and he knew tears were threatening to spill.

"He didn't tell me anything I didn't know, he just twisted it. And I promised you that it was a fresh start on the island. And then—"

"And then you broke the promise," she whispered, looking out the window.

When they returned to Kate's house Jack carried the little boy to his bed, grateful for the few seconds in the house. As much as he missed Kate and Aaron, he missed his home. He missed Aaron's height chart carved into the doorframe. He missed the way the house smelled like a mixture of vanilla and lilac. He missed the artwork and memos sprawled on the fridge.

"Umm… did he give you any, uh problems?" Kate asked, looking at the floor and smiling about her stuttering.

"I've never known you to be tongue tied," Jack teased, stepping closer. "Which was it, seeing me with Aaron or you watching my muscles when I carried him to bed?" He raised an eyebrow, toying with her.

"I was trying to decide what pictures to use when I replace some of the photos in the hallway," she fired back.

"Kitty's got claws," he smirked, resulting in an eye roll. "I'm going to win you back, Katherine Ann Austen. If it's the last thing I do, I'm going to make things right. I promise you, I'm going to win you back, Kate."

It was the slightest of smiles, but it was a smile that sprouted on Kate's face.
