i know it’s technically a reference to a past case but i like this idea bettergallifreysgaybar: Sure John knows to duck when he hears “Vatican Cameos” but how did he get that way. My theory is that Sherlock wanted to come up with a code phrase but instead of just telling John, he just randomly pops up when John isn’t expecting it yells “Vatican Cameos” and whipping a nerf ball at John’s head. Maybe first thing in the morning when John is sleepy, in the shower, when John is out on dates, etc.
I FOUND IT.
Here’s the reference I was alluding to in With Sherlock. Knew I’d seen it on tumblr.
OFC it’s the bloody brilliant reapersun
