Random thought for silly lightheartedness. Imagine after the whole plane scene at the end of the season, John and Sherlock are hanging out at Bakers Street & Sherlock is rearranging thing (say because his mind palace was rearranged too) & he finds his harpoon & starts whisking it about the air & John is all irritated & he shouts, “Stop shaking that spear /William/” & then stops & starts to giggle about William Shakespeare & Sherlock is just oblivious & is like STOP LAUGHING WHY ARE YOU LAUGHING?
