Holmes gives off the same odor as Merlin. he is depicted wearing a cape, his hat and smoking from a pipe, slender with pale skin and dark well combed hair with only a strand that dangled on his forehead, always soft spoken Englishman of his era, calculating and methodical and excellent violin player of which he prides himself.
While he appears dedicated to the cause of Chaldea, there are hints that his true loyalty may be to Proper Human History as a whole rather than to Chaldea. It is unclear what would happen if he were forced to choose between his Master and Proper Human History, and when directly asked this by Blatavasky he outright refused to answer the question. He has mentioned that there may be forces in play behind his selection as a Ruler that even he is not fully aware of, but what these might be is unknown.
"Elemental my dear friends" Holmes was walking with few servants through a corridor, heading to the command center where he would discuss some matters with Da Vinci, their conversation continued on the methods of how to preserve history and assist the arriving masters to Chaldea, but as the conversation continued, they passed an opened door where Sherlock side glanced and saw Moriarty giving a class of physics's and mathematics to the child-servants, while miniscule it was, both men threw a faintest glare at each other, but not stopping nor trying to seem fazed.
Holmes continued to walk as they bid their farewell, only a young member of the staff of Chaldea.
"May I help you young one?." Holmes asked with a smile as he lit his pipe.
