Season Six[]
Lex Luthor tasked him with keeping an eye on local farmer Jed McNally, who was Meteor Infected. Lex became angry with Dr. Bauer, after it was revealed to the public that McNally was a serial killer (a matter that Lex himself had not been informed about). After McNally was brought to Belle Reve, Lex had him moved to a 33.1 facility, where McNally was put under Dr. Bauer's care.
