Imagine me and you, Holmes does. Joan thinks about it day and night, its only right. To think about a case they love and hold it tight. So happy together.
In a rather uncommon honeymoon stage, the characters get to enjoy their newfound partnership, as well as each other's company, in a manner in which they have soon become accustomed. Watson can't stop smiling, Sherlock can't stop challenging her, they can't stop teasing one another: at the dry cleaner, at home or at the case of the week. For the time being, they have earned this simple, yet completely memorable, stage of bliss.
