Garrett usually lead tourists through the mansion, and offered a dry-witted account of the surroundings until he arrived at Gertrude Aldridge's door. There, he would spook tourists with a trick candle that fell over ominously after he told Gertrude's unsettling story.
However, after one tour, Garrett was spooked when Gertrude's door rattled loudly, the locks all flipping of their own volition. He ran for the front door, only to find its knob red hot. An unseen force then slammed him against the wall. Recovering, Garrett tried to toss a chair out the front window to escape, but the chair stopped mid-air then flew back and broke over him. Shouting, he ran for the first door he saw- Gertrude's. As soon as he entered, he bemoaned his mistake and tried to run back out. The door slammed shut behind him, and he soon found the stairway down coated in slime. When the basement floor started cracking open with green light, Garrett tried to run, but the stairway broke beneath him. Trapped in the basement, he dangled from the sealed door as a blue light washed over him. Staring into it, he screamed.
Later, when Erin, Abby, and Jillian arrived to investigate, he refused to go with them into the mansion and threw the keys across the road. The mansion's historian, Ed Mulgrave Jr, made a point of Garrett's confession to soiling himself during his experience.
- The Tour Guide was Katie Dippold's idea. 
- The Anti-Irish Fence was improvised by Zach Woods during filming.

Such a brilliant improvisor and so every take he was coming up with different things and then just made us laugh as it's so 'back in those days' like everything was so much prejudice and weird things against the Italians and Irish in our country so it felt like a good play on this old mansion."
