The director of The Mortal Instruments: City of Bones, Harald Zwart, has been interacting with fans on Twitter and Tumblr. Today he shared a sketch that he did of a padded cell for Luke.
"A sketch I did for the interior of a padded cell room Luke uses."
The padded cell would be a place where Luke could change into a werewolf and not hurt anyone. What do you think of the sketch?
