Disclaimer: I really wish I owned the show's characters or amazing dialogue, but BBC has the rights, so anything you recognize belongs to them.
Greg Lestrade should win an award for being the most patient DI in the world. At least he thought so. Brightly shining sun shone all around and Sherlock Holmes stalked around a crime scene, insulting everyone and everything in sight. Doctor Watson couldn't seem to hush the consulting detective, which made things much worse on Greg's throbbing head. The headache started early that morning and intensified as the day went on. Finally Sherlock rattled off a long series of brilliant deductions and everyone sighed with relief. As Sherlock bustled off, Lestrade noticed John watching him and trying to make a decision.
"So, what're you feeling with that headache? If you don't mind me asking that is," the doctor blurted after a bit.
"I don't mind at all. I could use some medical advice. My whole face hurts, it's gotten worse as the day goes on especially when I eat or drink."
"My thought would be a tooth causing the headache. I suggest calling your dentist and setting up a rush appointment."
"I haven't got a dentist at the moment, mine moved out of London."
John handed the detective inspector a card with Doctor Millar's information and wished him luck before calling for Sherlock.
Lestrade hated dentists. He wasn't afraid by any stretch, he just always got sick afterward. Nevertheless, he phoned the dental office and arrived there less than an hour later. The perky front desk smiled when he mentioned John referring him there and launched into a story about how sweet and lovely John was. Filling out mounds of ridiculous paperwork, Greg huffed at his predicament. He should be working on the case, not sitting around.
The blonde assistant led Greg to the office and Doctor Millar strolled into the room.
"Hello, you must be Greg," the jovial man remarked.
"That's me. Doctor Watson said you worked with Sherlock Holmes, I respect you greatly for that."
"Sherlock, quite a nervous man he was, shaking up a storm. In any case that's beside the point, what can I do for you today?"
Lestrade chuckled at the thought of a nervous Sherlock, then winced at the pain it caused his head.
"I've got a beast of a headache, but the pain's starting from somewhere on the left side of my mouth."
The dentist reclined the chair and Greg opened his mouth. Soon a nastily injured tooth was found to be the culprit and a root canal was the prescribed solution. Greg chose the newest Star Trek movie to watch, noticing that the villain reminded him of a a stronger, more homicidal version of Sherlock.
The procedure proceeded quickly and soon after the movie ended the dentist raised the chair.
"I'd suggest a good dose of painkiller when you feel the novacain wear off. You're free to go."
The dentist and the DI shook hands before Greg strolled out of the office trying to ignore his roiling stomach. He knew he couldn't make it home before giving in to his illness, but 221b Baker Street was nearby. He rushed in without knocking, causing John to leap up from his chair, Sherlock was thankfully nowhere to be seen. Ignoring the doctor's surprised inquiries, Lestrade dashed to the bathroom and vomited violently. John followed and knelt on the tile floor next to him, speaking soothingly and rubbing his back. After Greg finally recovered, he accepted painkillers from John and the two went out to get milkshakes.
