Molly Hooper was not one to make rash decisions. She always kept a clear head, even during frustrating moments at work. Her decisions were thought through and rational. She had made one decision that had no alternatives, and as she looked back on it now, she began to wonder if it had been a rash decision to let Sherlock Holmes temporarily move into her flat.

Mycroft had said that it would only be for a few days as documents were falsified to allow Sherlock to leave the country. Molly supposed that it was the right choice letting him live with her, because he wouldn't be safe anywhere else. He couldn't live with Mycroft; Moriarty's men might have suspected it. Molly was the person who didn't count, but she was the one who counted the most.

It was now day five of the new living arrangements, and Molly was nearly at her breaking point. She had seen Sherlock when he was bored before, but that was only in small fragments of time. Today was supposed to be his last day with her, but due to travel schedules, he would not be leaving for another two days. Molly could tell that Sherlock was at his own breaking point. Her kitchen had become a makeshift laboratory, and her living room was swamped with papers.

"Molly!" he shouted, tapping his feet restlessly against the floor. "I need chloroform!"

"Wait, what?" Molly asked, stepping into the kitchen. "What do you need?"

"Chloroform, didn't you hear me?"

"Why do you need chloroform?"

Sherlock looked up from the magnifying glass he was holding. They hadn't been able to bring any equipment into her flat just in case they were being watched, so Sherlock used anything he could find in her home. "For an experiment, obviously."

"What kind of experiment, Sherlock?"

"One that uses chloroform."

Molly searched around the room. "You're not planning on using my cat, are you?"

"Well assuming that I don't believe that you want me to use it on you, I believed it to be the rational substitution."

"No, you're not using it on my cat, and I'm not buying it for you!"

"Don't you think you're being a bit rash-"

"No I'm not!" Molly threw her hands up in frustration and turned around. "I know you're bored, Sherlock, but you have to start acting responsible! You're going to be on your own soon, and you can't be acting like a child."

"Molly, I am fully aware of what is happening around me. Any day now I will be leaving the country to gather information on Moriarty's web. Even though people believe that I'm dead, I am positive that there are some who believe me to still be alive. The time spent here is the safest I will be for who knows how long, and I need to know how to protect myself. This includes learning the effects of chloroform."

Molly shifted her feet. "Oh," she muttered, looking at the ground. "I'm sorry."

"No, I'm sorry," said Sherlock. "While you were out, I put on a disguise and bought chloroform. I did experiment with it on your cat observed the effects. He's safe and sound in your bedroom." Molly began to sputter and Sherlock grinned. "Since you're up, I'll take a coffee. Two sugars please!"

Molly ran to her room and saw that Toby really was safe. He greeted her at the door, mewing around her ankles. As she walked back into the kitchen, she wondered if it would be a rash or rational decision to put a sleeping pill in Sherlock's coffee.
