He usually spooks the tourists visiting the Mansion with his trick candle. However, one day things were different as after the tour he noticed the locks and the door knob on the door to the basement started to animate. He ran one way and found a doorknob to another door red hot, then was slammed against the wall. He then tried to throw a chair to break out a window, but instead the chair stopped mid-air, then hit him. He then ran down the stairs of the basement, before realizing it was covering up with slime. Stair broke and he was trapped in the basement with a reveal of Gertrude Aldridge. He screams in horror barely escaping the mansion.
Later when Erin, Abby, and Jillian arrived to investigate, he threw down the keys for them, but refused to go with them. The mansion historian Ed Mulgrave Jr. noted that Garrett had confessed to soiling himself during the encounter with Gertrude as well.
