‘Sherlock’ star Andrew Scott has come out in support of the Yes Equality campaign.

The fiercely private actor, who plays Professor Jim Moriarty in BBC show Sherlock, appeared at a Sherlock fan convention in London and took pictures with his numerous fans.

In the line of fans, there was a Twitter user known only as Fozzle who came well-equipped with Yes Equality posters, which she shared with Scott.

The out Pride actor took a picture holding one of the posters, which Fozzle then shared on Twitter.

Moriarty has spoken, all other arguments are invalid.
