Author's Note: My first crossover fic. I have all kinds of time this summer, so why not write? Plus, I kind of hated the end of Season 4 of Bones, and this is a re-write with House, just to indulge my fantasies. :)

Disclaimer: I own neither House, M.D. nor Bones.

Timeline: Bones - end of Season 4 (AU), House - Season 3

Pairings: Mainly Booth/Brennan and Chase/Cameron

"Booth, you need to go to the hospital," Brennan said. This was serious, and he had to understand that. Booth was hallucinating, which couldn't lead to anything good.

"I'll drive you," she continued, expecting some sort of protest out of her partner. When he said nothing, the worry only increased. He never missed an opportunity to argue with her, especially when it came to driving. Something was seriously wrong, she decided, as she helped Booth out to the car.

She drove him to the local ER, where they had to fill out several forms, before finally being told to take a seat. Brennan took the time to call Cam and tell her where they were.

Cam said everyone would be right over, and it was probably nothing to worry about. Brennan disagreed and told her so, but she appreciated the thought anyway. Then, they came and took Booth away. Brennan stayed in the waiting room when Booth asked her to. He knew he didn't want her to see him and his weakness, but she was hurt that he thought she couldn't handle it.

The others showed up moments later, Angela wrapping Brennan in a hug. "Oh, sweetie," she said. "He's going to be fine."

"You don't know that," Brennan said. "He was hallucinating, Ange."

"It's probably just stress," Angela insisted. "You did scare him with the baby talk and all."

Brennan nodded slightly, but she would only believe it when the diagnosis came out of a doctor's mouth, someone qualified to tell her what was wrong with Booth.

The team sat in silence for awhile before a doctor came over to them. "I'm sorry," he said. "But we think he has a brain tumor. We need an MRI to confirm, but it fits his symptoms."

"Are you a neurologist?" Brennan asked.

"Sweetie," Angela cautioned, touching her arm, but Brennan shook her off.

"Are you a neurologist?"

"No," the doctor replied. "I'm not."

"Then what makes you qualified to make this diagnosis?"

"We did the tests, except for an MRI. His symptoms fit."

"But it could be something else."

"It could be."

Brennan nodded. "I want someone qualified."

"Sweetie, I'm sure this man knows what he's doing," Angela said, trying to calm Brennan down.

"Angela, I want the best doctor we can find. If he or she thinks it's a brain tumor, then it is, but Booth deserves the best treatment. He'd do the same for me."

"I'm sorry," Angela said to the doctor. "Is there anyone you can recommend for us to see?"

"Dr. Gregory House at Princeton-Plainsboro in New Jersey is one of the best and one of the closest. He also has a neurologist on his team. We can get him transferred up there."

"Thank you."

"See, Bren, he's going to be fine. They're going to move him to one of the best doctors in the country."

"He might not be fine," Brennan insisted. "What happens if he's not fine?"

Angela didn't have an answer.
