Chase takes a few steps backwards, and it isn't hard to see the surprise on her face. She's hyper intelligent, yes, a genius, yes, but she's also four years old and right now Sherlock had just proved he was...well. Sherlock.

"Or maybe I just noticed the fact that you were bleeding and probably needed to go see a doctor which would mean getting dressed." Which was half-true, yes, but it's also merely a line to buy Chase time to collect herself.

She does, and smooths out her hair, picking up the clipboard and pen and making a point to tap the pen against the board.

"Sherlock with blue eyes I've known longer. And solved quite a number of riddles with him. It's familiarity."
