Dedicated to MegHolmes.

According to Sherlock's calculations, he and Molly had been married for forty nine years, seven months, three weeks, two days and 5 hours. This, among cases he was once involved in, was one of the many facts he rattled off whenever his grandchildren came to visit. Little Hamish and Josephine came to visit after school for a few hours while Greg Holmes and his wife Susan were working.

Molly was in the kitchen baking a cake with the help of Hamish when Sherlock decided to strike. His beautiful wife had always forbid him from turning their children and grandchildren into little robots. She often joked with Mycroft that she had put the devil in Sherlock. Today, however, Sherlock knew he had to strike because these kids were insufferable enough already. To add to this, they couldn't even deduce. Besides, Josie was getting bullied by the kids at school. Well, that's what he told himself to justify his actions anyway.

He was sitting in his old armchair that sat beside Molly's and faced the television. Little Josie was playing with her dolls on the ground, asking stupid questions such as "where did you get that dress?" and "what did you do yesterday?" Sherlock knew there was something wrong with this. She should just know.

"Josie, I have some things to teach you. You can't tell your grandma or parents, though. Ok?" he whispered down to her.

Josie looked up at her grandpa with suspicious, narrowed eyes. "What is it?"

"I have to teach you about mind palaces and deducing. Let's start with mind palaces."

~oOo~

Molly walked into the lounge room about half an hour later with little Hamish on her hip. Both Josie and Sherlock were sitting in a chair with their fingertips steepled under their noses, their fingers grazing their lips. Molly put Hamish down and crossed her arms while standing in front of Sherlock.

"Locked it away somewhere?" he asked and the little girl nodded before responding with a meek yes. "Great. Keep working on that, dear. When you want to remember something, just get an object to represent it and lock it away. A great example would be choosing a cake to lock away how angry grandma is going to be when we open our eyes." Mrs Holmes had one eyebrow arched as she looked down on her husband who opened his eyes and blinked at the light. "What a beautiful sight for my eyes to first lay on," he said with a smile before attempting to take her hands with his own.

"No, Sherlock. You promised me. You promised when we got married-"

"Forty nine years, seven months, three weeks, two days and 5 hours ago, darling."

"-that you would not turn the children and grandchildren into little robots. You promised me."

Sherlock stood up and brought Molly into a hug. "Her doll asked the other what she did yesterday. I had to intervene, darling, before it was too late," he rationalised in a whisper into his wife's ear.

"That's no excuse, Sherlock. Look at her. She's only beginning to understand basic things and you're trying to hijack her mind."

"Sometimes I wonder if you'd be this against it if you married Mycroft," Sherlock huffed, getting a small hit to his arm. "What was that for?"

"For suggesting I could have married him. I can hardly put up with you!"

"And yet, my darling, beautiful wife, you've done it for forty nine years, seven months, three weeks, two days, 5 hours and forty nine seconds. How do you do it?" he teased.

"Sometimes, I don't even know. You'll turn our Josie into a little Cyber Man like yourself." Molly pulled away from the hug and looked over at the girl who had long abandoned her dolls to investigate and explore her mind palace.

"No I won't. Dalek, maybe, by Cyber Man? Never."

Sherlock learnt fast to never compare his grandkids to Doctor Who villains without reaping the consequences from his wife.

~oOo~

"Erm, mum, is Josie alright? She's a little out of it. She's been sitting with her eyes closed for what feels like hours and when we talk to her, she gets angry and opens her eyes impatiently. Did something happen?" Greg asked when he called that weekend.

"Don't worry. I think I know what happened. I'll talk to your father about it and tell him the implications of- don't worry about it, dear. She should be ok the next time she comes over." When she hung up, she sent a death glare at Sherlock who was eating a piece of cake. "Look what you've done. Now Susan and Greg think we've broken their children!"

Sherlock shrugged before shoving the rest of the slice into his mouth. "Be grateful I didn't break Greg."

Sherlock was fast at learning the implications of not caring about his granddaughters solitude and threatening his child's mental wellbeing. He also learnt not to mess with the mental capacity of children by trying to enforce a mind palace and maybe forensic facts. Sherlock wasn't sure what he'd request she put in her mind palace. Forensics was very important, however. It was always good to learn things now for the future.

Molly was much more careful about leaving Sherlock alone with the grandkids. She didn't want him drilling in forensics, biology or chemistry facts. Of course, Sherlock slipped some extra homework for them about said subjects.

When Greg and Susan found out that Josie was exceeding the required knowledge and that she should skip a year, they were thrilled. Molly, however, heard the news and refused to be kissed by Sherlock for a few days.

"Look, Molly, in the end, I actually helped her intelligence. I'm pretty sure that introducing her to a mind palace and teaching her to deduce was a good thing. Besides, now she's making double the friends she had before."

"You taught her to deduce?!"

A/N: Hey guys!

This is the real "The Grandchild Mishap". I know I posted one before but that was the wrong story (obviously) and can be found in a previous chapter.

My apologies if I totally got the grandparent type characters wrong. I am neither a grandparent nor around awesome grandparents. They live a few hundred kilometres away from me and they haven't all retired. On top of that, my grandparents have been divorced and such. It's a rather confusing family tree. None of my grandparents have had children with the person they're married to at the moment. I hope I did ok.

Please tell me if I didn't or if you have suggestions.

My apologies to the requestor for my terrible writing for this. I haven't written grandparents before and I didn't really know what to do. I couldn't really base the characters off my own grandparents.

GAH! Rambles, sorry.

Poll is on my profile. Above the picture and stuff is a button saying "vote now" in blue. IDK, just press Ctrl + F and type in "poll". Won't take it down for a few more days because of this mishap. I was going to take it down today but I uploaded this wrong.

K, bye.
