You walked upstairs to the flat shared by the great detective and the blogger. You had just moved into 221c below them and you kept getting their mail.
You read the addresses on the envelopes as you walked into 221b. “Sherlock, I got your mail again. We really-,” you stopped when you saw Sherlock sipping tea in John’s chair and a dark haired man sitting in Sherlock’s chair. “Have I interrupted something?”
Sherlock stood and walked over to you. “Yes, but you already know that.” He snatched the mail from your hand and introduced you to the dark haired man without looking up. “(y/n), this is Jim Moriarty. Jim, this is (y/n). She moved into 221c a few weeks ago.”
Moriarty smiled and winked at you. You blushed and waved, “Hello.”
He smirked and sipped his tea. “Hello, Darling.”
You giggled and looked back at Sherlock who had looked up from his mail and was watching Jim with a protective glare. “She’s not part of the game.”
Jim glanced towards Sherlock and replied softly, “Everyone’s part of the game, Sherlock. They just don’t know it yet.”
You frowned and walked out of the room. The welcome you felt earlier was gone and you figured you should leave before it got worse.
