From cjnwriter - Lestrade gets hit on the head and thinks that he is Sherlock Holmes.
The Time for Threats
"Blah blah blah, I'm Sherlock Holmes, I make other people feel inferior! Ha! Look at me, making you feel inferior! FEAR MY POWER!"
"So help me Lestrade, I will bash you on the head again unless you-"
"Holmes! He is clearly suffering some kind of delusion as result of his concussion. Now is not the time for threats."
"But Watson-!"
"No arguments."
"But-!"
"Shh!"
"SHERLOCK HOLMES WILL NOT BE SILENCED! SHERLOCK HOLMES IS TOO ARROGANT TO BE SHHED!"
"Holmes just be quiet!"
"That wasn't me!"
