The Unexpected Arrival 44 (Parent!Lock)

Two streets away from 221B was a tiny corner shop where Mrs. Hudson occasionally took Hamish to buy sweets. It was far cheaper than the busy tourist shops that populated the area around the Underground and it had a little pick 'n' mix that had the best strawberry laces Hamish had ever tried. On the way back from the corner shop, Mrs. Hudson would hold Hamish's hand as he walked along a low wall and jumped off at the end, however on this occasion, Mrs. Hudson spotted her friend Dianna and stopped to have a chat. Hamish gingerly placed one foot onto the wall, wobbling slightly, but regaining his balance once the other foot was up. He slowly walked along the wall, to the point where there's a gap for people to pass through to the property. Hamish jumps this usually, with a little aid from Mrs. Hudson and a little run up. Hamish readied himself, and then ran at the gap and jumped.
   Mrs. Hudson turned round at the sound of Hamish's scream. The boy had fallen just short of the other wall and smacked his knee into the bricks, bursting the skin right through to the bone. "I'll call 999!" Shouted Dianna, reaching for her phone.
    Hamish was discharged from the hospital shortly, having had stitches and a lot of bandages put in place, and also a brace to stop him from bending his leg and re-opening the wound. As soon as he returned to the flat, John wrapped his arms around the boy and very nearly cried, "Oh Hamish!" He said, fighting tears, "Please never get hurt again! It worries us so much." Hamish pulled away from John and held his arms out to Sherlock who hugged him tightly, but slightly awkwardly seeing as physical contact wasn't his strong point.
"Be careful Hamish," Sherlock said, "I love you very much, don't get hurt."
    Hamish spent the rest of the evening playing chess with his leg propped up on a mountain of case notes. Sherlock had refused to play, John said it was because he knew he'd lose. John turned out to be rather good at chess, though was no match for Hamish and his tactics with the rooks. "Oh no!" John laughed as Hamish announced it was checkmate, "You win again!"
"You're letting me win." Hamish said
"No he isn't." Sherlock smirked from the kitchen, "He's been rubbing his forehead with his fingertips, you're just too good for him Hamish."
"Aww Sherlock." Mrs. Hudson smiled proudly, "You're very good at being a father." Sherlock smiled into his microscope,
"I know."
