A/N: Jumping forward in time a bit for some established relationship…
The microwave dinged and Molly opened it to find a steaming hot bowl of chicken soup. Smiling to herself, she extended her arms towards the floor, allowing the cuffs of the oversized cardigan she was wearing to fall down over her hands. With her hands covered by the sleeves of the jumper, she placed the bowl on the table. There were a great many advantages to dating a tall man, she decided.
"Is that my cardigan?"
The pathologist looked up, startled. "I… er – Mycroft! I didn't hear you come in!"
From the front door, Mycroft frowned briefly and then walked over to Molly and kissed the top of her head. "Darling, while I find it rather adorable when you attempt to wear my jumpers, I request that you refrain from using them as oven mitts, clever though the idea is."
"All right," Molly said a bit sheepishly.
As Mycroft removed his overcoat, Molly cocked an eyebrow. A cashmere scarf in a lovely shade of indigo, identical to the one that Molly's best friend Meena had given her years ago, was looped around Mycroft's neck. (Same knot Sherlock used to tie…)
"Er… Mycroft… is that my scarf?"
The diplomat sniffed. "Yes, well, the scarf is a perfect match for my tie, and I knew you wouldn't be going out…"
The pathologist smiled indulgently. "Don't apologise, love; it looks nice." She leaned up to kiss him, and when the kiss broke her fond smile turned into a Cheshire Cat grin. "I can't wait to tell Anthea you were wearing women's clothing!"
Mycroft rolled his eyes as Molly whipped out her mobile. While she was focused on her texting, he popped off to the hall closet and placed the scarf at the back of the top shelf, far out of Molly's reach. There were some advantages to dating a much shorter woman, he decided.
