"Do you think Elliot will like this?" Will asked, holding up a white t-shirt with the Eiffel Tower on it.

"How the hell would I know?" Karen responded, looking up from the French fashion magazine she was flipping through. Will chuckled and pulled the shirt from the rack, walking to the little window where the cash register was. They were at a sidewalk souvenir shop, making fun of all the tacky tourist gifts and grabbing some for their friends back in New York.

"Will?" Karen asked suddenly, wrapping her arms around him from behind as he waited for the sales person to bag up his purchase.

"Yeah?" he asked, extending his hand to take receive his change.

"When are you going home?" she laid her cheek against his back.

"Merci," Will told the sales person, taking the white plastic bag from him before lifting one arm and turning to wrap it around Karen. "In eight days."

Karen looked at him, surprised. She didn't know he had set such a definitive time table for this trip.

"You booked a flight?"

"I did," he affirmed, leading them down the winding path back towards his hotel.

"I don't understand…" Karen began. Will knew exactly what she was thinking.

"Karen….I-I had to put some boundaries on this," Will told her, shrugging. He didn't need to say the words for Karen to know he was referring to their affair. Karen broke away from him, sliding her hand down to find his. She laced her fingers with his as she spoke. Her voice was quiet and timid, and Will knew he was witnessing the rare, vulnerable side of Karen. The side he knew he needed to take the most care of.

"But…why?" she asked him, shyly meeting his gaze. "Don't you want this to last forever?"

Will suddenly stopped walking, and grabbed her arm roughly to make sure she stopped also. He dropped the bag he was holding onto the concrete next to him and grabbed her waist tightly, pulling her close. Suddenly Karen felt herself being dipped backwards, as Will kissed her fiercely, his strong arms around her waist and her back. The gesture was romantic and uncharacteristically bold for Will, so Karen couldn't help but smile when he broke their kiss and set her back upright.

"Of course I do," he told her, looking deep into her eyes. "More than you could know." They continued walking. "But Karen, nothing's changed for us. There is still no way we could ever be together." She reluctantly nodded, acknowledging the sad truth of his words. The rest of the walk back to the hotel was silent as the pair pondered how their future together would play out.

Two hours later, and Karen was flat on her back as Will pulled out of her. He balanced his weight on his forearms, leaning over her to kiss her sweaty collarbone. He sighed as he rolled onto his back next to her, listening to her catch her breath. After a minute, she sat up on the edge of the bed, pulling the white sheet around her naked body. Will reached between his legs to remove his condom.

"Huh," he mumbled, pulling his hand out from beneath his sheet to examine the used rubber.

"What?" Karen asked, securing the sheet under her arms like a towel.

"It broke," Will uttered, in disbelief. "In all my years of using these, I've never actually had one break." He shrugged and pulled a tissue off of the bedside table next to him to wrap the condom in. Karen watched his nonchalant actions in disbelief.

"Shit, Will!" she exclaimed. Her anxious tone startled him and he turned to look at her as she stood from the bed, the sheet wrapped around her like a strapless dress. Her hair, which was curling around her face as the sweat dried in it, fell loose around her shoulders.

"What?" he asked. "It's no big deal, right? I'm clean and you're on the pill."

Karen didn't say anything, just stared at him, her eyebrows furrowed.

"Right?"

She took a deep breath and tried to answer him calmly.

"No, Will, I am not. I told you that Stan and I were trying to get pregnant. I haven't taken a birth control pill in a year."

The color drained from Will's face and he suddenly felt nauseous as Karen began to pace the room in front of him.

"Well….I mean, it's probably fine right?" he asked, the nerves resounding in his voice as it rose in pitch. Karen shrugged.

"I don't know, is it?" she paused her pacing. "I haven't gotten pregnant in a year of trying so chances are good that I won't from this one time," she explained, "but….what if?"

Suddenly Will was at her side, wrapping his arms around her. He didn't know what he could possibly say to make her feel better. On the one hand, his heart was leaping at the thought of having a baby with Karen. He couldn't deny that it was something he had been thinking about since the night before when they were at Claire's place. But no way in hell would Karen getting pregnant be a good idea. What would she tell Stan? How would they tell Jack and Grace?

As they stood there in their embrace, Karen too was running through all the possibilities in her head. If she was pregnant, she could tell Stan it was his. No, that wouldn't be fair to Will. Or Stan. She could leave Stan immediately upon their return to New York and raise the baby with Will. No, she couldn't do that. She wouldn't get any money from Stan, they'd be able to trace her pregnancy back to before they split and he would know she had been unfaithful. And she wasn't entirely sure she was ready to leave Stan. She sighed. But, it might be her only option.

"Wait!" Will exclaimed, pulling back to look at Karen's worried face. "Can't you get a morning after pill or something? Doesn't that usually work? Wouldn't that end it?"

Karen licked her lip and nodded slowly.

"Yeah…." She began. "But honey - I'm not sure I want to."
