John saved the day! Sherlock is grateful.
It makes sense that being around Sherlock enough causes John to start seeing things a little differently, start to hone his observation skills. :)
Grateful
Sherlock felt guilty, which was peculiar for him.
John had practically solved the last piece of this case for him with a reminder of something as human as how sloppily people organize their wallets. It hadn't even crossed Sherlock's mind, for whatever reason, but he knew that he hated conventional methods of reasoning such as relying on habits that some didn't even have.
Sherlock looked at John, feeling a cerise flush creep up.
I'd be struggling over this until the morning if it hadn't been for him. ...Well, that's something I'd never thought I'd say.
I'm glad he was here.
