"Molly could you hand me your notes?" Sherlock asked. She rolled her eyes and dropped the notebook onto the lab table with a loud smack. John was taken aback by the sudden change in attitude.

"Anything else you want?" she asked in a tone feigning sweetness.

"Well maybe I—" he faltered when Molly glared at him. "Nevermind."

"Are you two alright?" John asked quietly to Sherlock. This behaviour had been going on for nearly five days, though John was just now experiencing it himself.

"Fine; an overreaction on her part," Sherlock remarked.

"Overreaction?" Molly asked incredulously.

"Well, you are being over-dramatic about the whole thing," he argued.

"Says the drama queen, himself," she retorted.

"Look, you know that I delete information about the solar system in my mind palace, so why does it surprise you that I have absolutely no opinion on the matter?" Sherlock asked.

"Solar system?" John muttered to himself, officially confused.

"It's just the point that you chose the wrong opinion when I presented it to you," she huffed. "Pluto is, in fact, a planet; it doesn't make it any less of one just because it's smaller than the others. Pluto matters to the solar system and those bloody astronomers are saying that it's insignificant and it doesn't count."

"Molly," Sherlock caressed her name, "darling, I think I know what the issue is." He realized how much her argument resonated with that of the way she used to feel when he treated her as if she were insignificant. A wave of guilt washed over him. They had been living together for two months now and the honeymoon period had faded a bit fast for both of them.

"A planet? That's what this whole thing was about?" John chuckled in disbelief.

"John, could you vacate the premises? I need to speak with Molly alone," Sherlock told him. The good doctor took his exit, leaving the quarreling lovers alone. "This is definitely not about Pluto, is it?"

"It is," she insisted. "Mostly." Her arms were crossed and a sad pout was displayed on her face as if she had reverted back to childhood.

"What is this really about? I know you're not truly upset that I don't care for the solar system," he asked with concern, taking her hands in his. She stood before him as he was still seated on the stool.

"I don't know, it's silly," she attempted to laugh it off.

"Molly, whatever it is, it's clearly bothering you," Sherlock pointed out. "It's not silly." He studied her face and noticed the makeup covering up what appeared to be dark circles beneath her eyes. "You haven't been sleeping well."

"Really, it's fine, Sherlock.," Molly insisted. "I'm sorry. This entire argument has been an absolute waste of time and it's fine. I'm fine."

"Could you please stop feeling like a hindrance and allow me to fix whatever is wrong? If it's something I can't fix, then at least I can listen," he told her softly. "Please?" Sherlock brought her knuckles up to his lips. "I love you."

"I just miss you," she said quietly. "I miss the snogging for hours on end and you don't lie with me in bed as often anymore. Of course, I don't expect you to whilst on a case, but I find it hard to sleep without you. Hell, I can hardly get a quick kiss on the cheek anymore."

Sherlock's face dropped as he realized how neglectful he had been lately. He hadn't meant to be, but having a flatmate again had him reverting back to how he acted with John. Molly was much more than a flatmate, though; she was his beloved and he had regretfully begun to let things slip.

"I am so sorry, Molly; I didn't even realize how neglectful I was being," he apologized.

"S'okay," she shrugged off, but it wasn't okay; not to Sherlock.

"I will make this up to you as soon as I close this case," he told her. "I do love you. You know that, right?" Molly nodded her head silently, a small smile forming on her face. Sherlock pressed a tender kiss to her lips and savored it, realizing it had been much too long since they had a truly good snogging. He regretted having to pull away from her to finish his specimen study, but he felt her squeeze his hand affectionately and knew things would be okay.

Author's Note: how's that for a creative argument? damn, this chapter was tough until it all clicked lol
