Rigsy

Rigsy was a graffiti artist from Bristol, whose criminal activity saw him sentenced to community service. He helped Clara Oswald fight the Boneless. Rigsy attempted a self-sacrifice to ram an empty subway commuter train into the Boneless, which needed a person or object to hold the dead man's lever in place so it would remain in operation. Clara, however, used a headband to restrain the lever and let the train run with nobody inside, saving Rigsy from an unnecessary demise. (TV: Flatline)
