|This article is about the TV Series character. You may be looking for his Comic Series counterpart. For other pages with the same name, see: Sebastian|
Nothing is known about Sebastian's life prior to or as the outbreak began, other than he came from a political dynasty family, similar to the Kennedy family and the Bush family.
At some point during the outbreak, Sebastian lived along with his mother in the community in Charleston, West Virginia that she presumably founded.
Later, as Eugene and Stephanie are moving on to the next area to clear, they notice several walkers approaching a distracted Sebastian and Kayla. After the two defend the couple from the walkers, Sebastian yells at Eugene for 'ruining their date', causing the two to argue. When Stephanie accidentally splatters Kayla with blood while defending her from another walker, causing her to scream in horror, Sebastian becomes more aggravated with the two, provoking Eugene into punching him in the nose. Mercer, Lance Hornsby, and a group of Commonwealth soldiers quickly arrive at the scene. Sebastian berates Mercer for being absent during the situation, and they take Eugene away.
This list shows the victims Sebastian has killed:
- Possibly numerous counts of zombies
