Well, this is my first try at a follow-up to a Bones episode. Let me know what you guys think!
My thoughts on what might happen if Booth felt guilty over lying to Brennan. Considering how he seems to suffer from what Bones calls his "Catholic guilt" (mind you, I was raised Catholic and am not knocking the religion), I could see the fact that he lied to someone he knows means so much to him making it difficult to sleep to the point of him having to admit to her that he wasn't truly honest.
A sharp knock the door interrupted Brennan's late night work on her most recent novel. She quickly saved her work and set her laptop on the floor by her feet. Moving to the door, she peered out and was surprised to find Booth fidgeting outside her door. She opened the door and his gaze snapped up from the floor to meet hers.
"I lied to you," he said, almost looking surprised himself as he said the words.
"I know," she replied, turning and retreating inside, leaving him to follow. She moved her laptop farther out of the way and sat back on the couch with her half-full glass of wine in hand.
He followed her in and watched as she sat and then began to pace, running his hand through his hair every few minutes.
She watched him, waiting him out. He would say more when he was ready. She sipped slowly, enjoying the chance to observe him. He had obviously been in bed at some point. His hair was mused and his eyes carried the glazed look of someone who had only been up a short time. He wore a worn, navy blue FBI tee and loose gray sweatpants that sat low on his hips. It wasn't hard for her to picture them having a completely different evening together. They would be sitting on the couch together, instead of her alone and him at his place, in bed. She would sit with her feet in his lap as he propped his up on the coffee table and watched a hockey game. She would be working on her book, but distracted from time to time as he would lightly brush his fingers over the soles of her extremely ticklish feet.
He finally stopped and faced her head on. "I should never have said it."
"Booth, no…"
"Just let me say this, Bones; then you can talk all you want." She sat back with a slight nod of agreement and let him have his say.
