Nothing is known about Gavin's life before or as the outbreak began, except that he was a doctor at St. Ignatius Hospital in Atlanta, Georgia, working as an oncologist. He and Dr. Steven Edwards were former colleagues.
Gavin was found after he fell from a first floor apartment building trying to get away from walkers. Dawn Lerner wanted Gavin alive at all costs, as he was a doctor, however, Steven Edwards thought he couldn't save him, as he had internal bleeding and a collapsed lung. Beth Greene (under orders from Steven) injects Gavin with 75mg of clozapine, causing him to seize and then flatline. Gavin is then put down by Dawn before he can turn. Beth later finds out that Gavin was a colleague of Steven's and he purposely made her inject Gavin with the wrong medicine so that he could remain the only doctor at the hospital, ensuring that he didn't become disposable to Dawn and the other officers.
This list shows the victims Gavin Trevitt has killed:
- Possibly numerous counts of zombies
Steven purposely told Beth to give him an injection of clozapine, knowing the resulting reaction would cause a seizure and kill him while Beth didn't know because Edwards feared Trevitt would take his place at the hospital.
- Dawn Lerner (Before Reanimation)
After he died, Dawn stabbed him in the head with scissors before he could reanimate.
Gavin and Steven presumably had a good professional relationship. However, it is unlikely that they were anything more than acquaintances, as Edwards has no issue with killing Trevitt in order to preserve his own life.
- "Slabtown" (No Lines)
