Black Swan

The Black Swan is a character who first appears in "UnmAsked". Spencer finds the sketches for Black Swan's costume in A's lair, and Aria, Emily, and Hanna spot her at the Masquerade Ball. Her identity is unknown, and will be a mystery for Season Three. Before Mona disclosed to Spencer that she was "A," Spencer, Hanna, Emily, and Aria believed Black Swan may have been "A".

Black Swan is seen talking to Lucas and Jenna at the Masquerade Ball.
