If Sherlock takes sugar in his tea (and John doesn’t) does this mean that Sherlock has a sweet tooth? Furthermore, does this mean that Sherlock really secretly loves cake? I am now imagining Sherlock getting super into baking anatomically correct cake versions of bodyparts and eating them, leaving everything a complete mess but John having no idea what’s been going on except one day he shows up early and Sherlock’s in the kitchen with half a leg on the table and a forkful of foot in his mouth.
