Parent!lock AU - It’s like they say: “Like father, like son.”
In his tenure as unofficial showrunner of the British Government, Mycroft hasn’t quite ever encountered true domestic bliss. The job revolves around dealing with the natural dysfunction of society, and happiness is never something that flourishes easily under those conditions. But then again, Sherlock and John always did insist on being exceptions to everything, didn’t they. Hamish Holmes-Watson, of the grand age of three years, two months, and twenty-four days, takes advantage of Mycroft’s inability to deal with domesticity and smushes his peas onto his dish with abandon, grinning with delight at the green smudges blooming on his plate.
At least Hamish is sitting in a high chair. Mycroft smiles down at his nephew, seated a safe distance away between him and the spit and smashed peas.“And look who’s here,” he says. “Hello there, Hamish.” His smile won’t stay plastered on his face, and slides off quick. He sighs. He doesn’t have anything against Hamish, really, but good grief must children be so messy? Hamish gives Mycroft an impossibly wide grin.
“IDIOT!” Hamish says, banging his hands on the table. Mycroft squeezes the handles of his umbrella tighter. Excellent parenting there, Sherlock. (Full Ficlet on AO3)
