Marcus has an intense phobia of elevators. When he was fifteen years old, he was trapped in a dark, malfunctioning elevator for several hours during a power cut, experiencing severe panic and shortness of breath.

He always climbs up many flights of stairs to avoid using elevators, which instantly makes him feel calm and relieved.
