Sydney smiled in satisfaction as she put the final decoration in its place. Today was Ophelia's third birthday and she was throwing her a small birthday party.

"Ding dong!" Ophelia shouted as the doorbell rang.

Sydney opened the door to see Weiss with a present. "Weiss, hey!" she greeted him.

"So this chick finally agreed to go out to dinner with me but I told her I had a party. She asked if there would be booze and I told her no, it was my 3-year-old friend's birthday party. So yeah, that went well." he babbled as he entered the house.

"You're such a good sport." Sydney laughed.

The doorbell rang and more people began to pour in, Vaughn and Lauren were last.

"Hi." Sydney said as she forced a smile.

"Hello." Lauren responded.

Vaughn just smiled and handed Sydney Ophelia's present.

"Well," Sydney said as she entered the dining room, "it's time to cut the cake."

"A big piece would be nice." Weiss joked.

After everyone sang happy birthday, Sydney cut the cake and of course Weiss got his big piece. The doorbell then rang once again, which confused Sydney because everyone she had invited was already there.

She walked to the door and slowly opened it to see Sark standing there. "What do you want?" she asked tightly.

"You didn't think I was going to miss my daughter's third birthday... now did you?" Sark replied sarcastically.

Sydney rolled her eyes and snatched the gift out of his hands. "I'll be less than pleased to tell her you stopped by."

"This is no fair." Sark crossed his arms. "I'm her father, I practically raised her."

"My apologies to her for having a person like you to raise her. Now if you'll excuse me I'll take over where you left off." she began to close the door but Sark forced it open and walked into the dining room.

"Sark!" Ophelia said happily as she ran to give him a hug.

"Hey there princess." he said as he hugged her.

"What is he doing here?" Vaughn asked angrily as he looked at Sark.

"He was just leaving." Sydney answered as she glared at him.

"May I talk to you?" Sark asked after he put Ophelia down.

Sydney nodded and led him to the hallway. "Make it quick."

"I thought you might like to see these." Sark said as he handed Sydney the package of photos.

Sydney flipped through the photos to see a man with a younger Ophelia. "Who is this?"

"His name is Vladimir Kaminski. Before the CIA found Ophelia he had kidnapped her. No one knows what he did with her but now he's posing threats." Sark reported.

"What do you mean? He's threatening you?" Sydney asked.

Sark nodded. "I'm afraid he's going to try to come after Ophelia again."

"Why do you care?"

"Whether you like it or not, Ophelia's my daughter just as much as she's yours. You need to accept it whether you like it or not." he answered offended.

"Why are you telling me all of this?" Sydney questioned as she threw the pictures into his hands.

"Because I'm worried about the safety of our daughter. I think that you should let me stay here with you two until he's taken care of." Sark said.

Sydney laughed at his absurd idea. "There is no way that's going to happen."

"If Kaminski believes that we're together he won't hurt you."

"Why is that?"

"He won't think that you're a CIA officer if you're living with me. Look, I think that we should work on finding out what Kaminski did with Ophelia together." he insisted.

"I still don't see why I should let you stay here with me." Sydney replied not yet fully persuaded.

"Look, if I'm here there's no way he's going to get anywhere near Ophelia."

"But I can just inform the CIA and I'll get them to secure the house."

"Then he'll be suspicious. He'll think that I'm a double agent for the CIA." Sark argued.

"You aren't, so as long as you know you'll be fine." Sydney rolled her eyes.

"Sydney," Sark began, "do you care about Ophelia?"

"Of course I do!"

"Then do this for her. Can't we just put aside our differences to protect her?" he asked.

Sydney sighed. He had a point. "Fine."

"Another thing," he smiled, "you can't tell anyone."

"So what, I have to pretend that we're actually together?" Sydney replied disgusted.

"Yes but only for a little while."

"Fine." Sydney said as she walked away.

"You're still here?" Vaughn asked as Sark reentered the dining room.

"Surprise." Sark grinned. "Sydney and I decided to put aside our differences and become a family." he said as he wrapped his arm around Sydney.

A surprised Sydney played along and forced a smile.

"Ha, I won't believe that until I see you two kiss." an entertained Lauren spoke up.

"There's no need for that." Sydney said quickly.

"Oh come on!" she pressed on. "It can't be that disgusting... you did have to do more then that with him in order to create Ophelia."

Sydney slowly reached up and pecked Sark on the cheek.

"Oh come on!" Weiss said in dissatisfaction.

Sydney rolled her eyes. "I'm going to get a gulp of fresh air." she said as she turned and left.

"Alright, don't be too long lemon cake." Sark winked at her.

"Lemon cake?" Sydney mouthed to herself in disgust. She prayed that she'd have the strength to go through the rest of the night and the next few weeks with Sark.

After everyone left and all the dishes had been clean, Sark came up behind Sydney and whispered in her ear, "Now that I'm here, that nightlight won't be necessary."
