After he left, and Abby, Erin, and Patty moved on, but Holtzmann hung back to photograph the final image. He headed out the revolving exit nearby and told her goodbye. He declared 'no ghosts allowed.' Patty took his can, and sent him on his way. Patty made him stop, and told him to remove the ghost, which he acted on as another art direction and kept spraying. He told himself 'no ghost' and promised to fix it. He asked her to confirm she didn't it on the wall anymore. Patty stated she didn't want graffiti on her wall. He looked at her but sprayed one more time. She instructed him to look at her and stop. Patty retorted he wasn't helpful for her. Patty insisted she couldn't or she would get fired. Abby wanted him to continue so she could record the visual. Abby got out a small notebook to take notes. He started spray-painting a ghost on the wall. The Graffiti Artist held out his hand to stop her then started spraying. He replied that he had, to Patty's amazement. Erin rephrased the question and asked him if he saw a ghost. Abby insisted she was being specifically clear. Annoyed, Patty asked her to speak English. He asked if she was talking about a boat. Abby interjected and asked him if he ever saw a Class 4, semi-anchored entity anywhere in the vicinity. He clarified his studio was in SoHo and the station was more a gallery to him.

Patty quipped he thought it was his art studio. When she added that he was always down here, Abby became interested in him as a potential witness. She warned him before to stop tagging the walls. Patty expressed annoyance with his presence and told him to stop what he was doing. While Erin Gilbert, Abby Yates, and Jillian Holtzmann were investigating Patty Tolan's ghost claims, they encountered the Graffiti Artist on the subway platform.
