Sherlock Holmes was not an affectionate person. Everyone knew it and Sherlock himself knew. He was never that caring. He was rude and always in his own world. He walked over everyone that was below him and his ego was inflated. For one of his cases, he needed to befriend a woman named Ellie. She worked for a big company that Sherlock needed to get into. He didn't care for Ellie. Not one bit. She was important for the case but after that Sherlock never called her again.
It was only two months later, she showed up at his front door. She was yelling, as Sherlock stepped to the side to let her in. John looked confused to see a very angry woman in the room. "I can't believe you got me pregnant!" She yelled, shoving Sherlock. He didn't react much.
