A respectable physician in Columbia, Dr. Pettifog was put in charge of implanting Elizabeth with a mind-control device on Father Comstock's orders. In doing so, he expressed no empathy for her, but rather only scientific interest in the procedure. When Booker DeWitt arrived at Comstock House and deactivated the Siphons limiting Elizabeth's powers, she opened a Tear to a field ravaged by a tornado. The gale swept up the scientists and destroyed the operating theater.
