Remember Sebastian Wilkes (Bertie Carvel) from 'The Blind Banker'? According to him, he and Sherlock graduated from the same university.One of the books Sherlock pulls in attempting to crack the book cipher is Charles Darwin's On The Origin of Species - Benedict Cumberbatch played Joseph Hooker in the Darwin biopic Creation.It's not until 'The Final Problem' that he finally gets it right. Accidental Misnaming: A Running Gag from series 2 onwards is Sherlock always getting Lestrade's first name (Greg) wrong.
