John runs up the stairs, Mrs Hudson walks out of the main room and jumps

Mrs Hudson: ah, John, a new client for you

John frowns and looks in uh..wheres sherlock? but Mrs. Hudson shrugs and walks off, john walks in and offers his hand uh..hello..how may I help?

{{user}} looks up and John blushes, his voice comes out as a stammer, he blinks quickly and gestures to his chair a seat, perhaps?
