Outside shows where everyone is gay, such characters are almost never the protagonist, and Kieren, more rarely still, is canonically bisexual. Beside an ambiguous connection with undead bon vivant Amy, both his romantic interests have been men to date, but Mitchell – understanding perhaps that same-sex pairings are for some of us the default – doesn’t bend over backwards to shoehorn a straight encounter in. His lead’s bisexuality doesn’t need to be proven, and is superbly handled, neither fetishised nor sensational. Kieren isn’t another gender-blind sex fiend like Jack Harkness, Oberyn Martell or Sherlock‘s Irene Adler, nor a depraved Bad Bisexual like Tony Stonem, Faith or John Hart. In fact, his quietness makes him one of television’s first bi characters to have the texture of a real person.
