"Dr. Brennan? I'm Dr. Villarreal, the ER physician. I've called in our gastroenterologist. Based on the white blood count, nausea, and pain, we believe your husband is experiencing appendicitis. If Dr. Bloom confirms the diagnosis, she'll probably recommend that your husband have surgery immediately."
Brennan exhaled slowly. Appendicitis would explain a lot of Booth's symptoms. He'd had extreme pain in his right side and had run a high fever. He said he could tough it out, but finding him on the bathroom floor writhing in pain told her he needed immediate help. However, pain wasn't the only problem.
"Dr. Villarreal, I do need to ask one question. Why would my husband hallucinate? That's not a normal symptom of appendicitis, is it?"
"Some people experience febrile hallucinations when their temperature is elevated. Since his fever was 105 degrees when you arrived here he could've experienced them. Was he hallucinating?"
"Well, he was going to drive to the ER in Antarctica, he said he saw Santa Claus, he was talking about arresting a singing frog, and he thought he was John Wayne leading the cavalry, all in the 15 minutes it took us to drive from our house to here. There were also other vague ramblings about a hockey player named Luc Robitaille. My husband has hallucinated about him in the past."
"I understand." Dr. Villarreal looked at her laptop screen. "I see that when your husband had the brain tumor he hallucinated, but I don't think the things he has experienced today are related. I think they're caused by his fever. We're working now to reduce his fever and I think that will put an end to these disturbances. Your husband's been asking for you. I'll take you back to see him."
"Thank you."
Brennan entered Booth's cubicle. "Hiya, Bones! Ready to go to Mars?"
