He can be best described as the gearhead that loves working on old cars.
Trevor, along with his sister Phoebe, moved with their mother Callie to their grandfather's old rundown farmhouse near the town of Summerville. He explored an old collapsing barn and removed a tarp covering a retro ambulance. He then made it his mission to get it running. Once he got it started, he took it for a joy-ride in the nearby fields. Trevor, along with some new friends from the nearby town of Summerville, cruised in a car and for fun hung out at an old mine shaft opening, while getting to know local girl Lucky. Soon they both witnessed something that could only be described as supernatural, with something coming out of the mine in broad daylight.
Later, along with his sister and her schoolmate Podcast, they chased after a ghost that had been in a mining company building, that was now causing problems in Summerville. With Trevor at the wheel and Podcast along to help, Phoebe got to try out the Proton Pack attached to the gunner seat in the Ecto-1.
