Part of the 1000 Themes Challenge Number 779

A/N: This little one shot was inspired by the song "Lie." Even though it is almost the exact opposite of the idea of Lie to Me, I was thinking about the show (and Callian) while listening to it. I got this idea from the lyrics. It's a bit of a sad little fic, but I might do a sequel or turn it into a multichapter if anyone actually likes it... And I'm not certain that anyone will cause I don't love it myself.

Lie to Me

"So lie to me tell me that it's gonna be alright. So lie to me tell me that we'll make it through the night."

~ "Lie" by David Cook ~

She had told herself that she would tell him everything. She was going to tell him about Alec cheating on her. She was going to tell Cal how she had really come to feel about him after all the years they had spent together. But all those plans evaporated the second she opened his office door and saw him. And saw them.

It was Cal and Zoe, locked in a passionate kiss. They broke apart, Cal with an expression of surprise and shame. And Zoe? She wore a smug smile, seeming pleased that Gillian had chosen that moment to burst in. Which she probably was, considering her intense dislike for Gillian.

"Gill-" Cal started.

"Save it, Cal," Gillian said through the tears that pooled in her eyes. So Cal wouldn't see as a few spilled over, she turned away from him and walked with carefully measured steps down the hall.

"Foster!" he called after her.

Gillian picked up her pace, breaking into a light jog. She heard hurried footsteps following her.

"Gill," Cal said, grabbing her shoulder and spinning her around. "Gillian, I'm sorry. You weren't supposed to-"

"To see that?" Gillian asked, angrily cutting him off. "You didn't want me t-to see how much you love her?"

"That's not what happened, love," Cal said softly. "Zoe-"

"Cal, don't lie for her. Look, I really don't care."

Cal paused. After a few seconds, he said, "Of course you do."

"Hell Cal…" Gillian trailed off, shaking her head slowly. She wiped her eyes with the back of her hand. "We both know that you love Zoe."

"No, I don't."

"Don't even bother denying it."

"Dammit Gillian, why do you believe me when I lie, and not when I tell the truth?"

"Then lie to me now," Gillian said. "Lie to me and tell me that… that everything will be alright. Tell me that you love me. Just lie."

"Gillian," Cal said. He cupped her face in his hand, reading every flicker of emotion that crossed it. "Gillian, I do love you. I would only be lying if I told you I didn't. Zoe was just… She came on to me, not the other way around. Gillian, look at me." Obediently, she met his gaze. "Do you believe me?" Cal asked.

For a moment Gillian wanted to say no, to childishly stick to her original argument. But she just whispered, "I guess I do."

"You guess?"

"I believe you, Cal." There was doubt on her face, though. She didn't really completely believe him. That might have been a good thing, though. Anyone that wholly trusted Cal Lightman was a fool.

So he just said, "Good." Cal smiled ever so slightly and kissed her lightly on the lips.

Gillian blushed and pulled away from him. She dropped her eyes, suddenly very interested in the tile pattern.

"Zoe's probably waiting for you," she mumbled.

"She can wait."

"Cal?" Gillian asked quietly.

"Yeah?"

"You never told me that it would be alright."

"You know that I can't lie to you," Cal said gently.

"I need you to," Gillian pleaded. "Lie to me, Cal. Just this once."

"Why?"

"I need to hear you say it. It's all I ask. Then you can go back to Zoe or whatever you-"

"Why won't you get it through your head that I do not like Zoe?"

Gillian sighed. "Please?" She thought that maybe if Cal told her everything would be alright that she would believe it. Hope was the one thing she needed more than ever now that Alec was gone, and she was alone. Gillian always believed Cal; it was the one thing she was counting on now.

Cal drew her up against him. "Gill, it's going to be alright," he whispered in her ear. "Don't worry." And he meant it. He knew that everything was going to be alright because he had Gillian, and she had him.

Gillian closed her eyes, letting herself believe what she thought to be a lie. A lie, that's all it was to her. A lie, like everything –and everyone – else in her life. If only Alec and Zoe were gone. Then maybe the lie would miraculously turn true. If only they were gone, if only Cal was hers… If only Gillian had a single ounce of hope left in her being. But she didn't. Not enough to fight the dark depression that was slowly overcoming her.
