Dying to play James (Jim) Moriartyfrom BBC: Sherlock once more after watching some again tonight. Would love to play him against most all pairings, and even playing the version of him that is inside Sherlock's mind palace would be fun. I also play Mycroft Holmes and Sherlock Holmes and miss Mycroft as well!
Also play a cocky Jack Harkness from who and love him against just about everyone (Rory, Doctor, Ianto, etc.)
