Logan first appeared in the episode The New Guy. He was hired by an unnamed individual to disrupt a banking convention. He used William Shakespeare's Lost Folio to achieve this. His first killing was of a news reporter doing a story on the banking convention. His second killing was of a waiter who worked at the hotel where the banking convention was being held. After that he tried to kill Steve Jinks, who was saved by Myka Bering by reading the text on the paper. He then attempted to kill the three bankers present but Myka Bering managed to save them in time. After reporting back to the person who he works for, he was suffocated by Sally Stukowski, the lead FBI agent on the case. It appears that these three were working together to learn everything possible about Warehouse 13.
