||Zach Salvatore, played by Chris William Martin
Zach Salvatore was a distant nephew of Stefan and Damon Salvatore. He lived alone at the Salvatore Boarding House until his vampire uncle, Stefan Salvatore came to live with him after a short visit. He was unhappy about this, especially after a number of "animal attacks" in town. He also didn't like the presence of Stefan's brother Damon Salvatore who came to Mystic Falls due to the fact that he followed his brother to torment him.
Zach showed Stefan that he had been growing vervain in the basement and they could use it to stop Damon from hurting anyone else. They failed at the first attempt but Stefan managed to spike Caroline Forbes's drink with vervain, thus weakening Damon when he bit her. Zach later visited the basement where they had Damon locked up. Zach told him that he had vervain in his system for several years and it wouldn't help to kill and drink his blood. Damon tried to strangle Zach until Stefan saved him.
Damon showed he still had an influence over Caroline and compelled her to free him. He attempted to kill her for blood but Zach tried to stop him. Damon broke Zach's neck and pursued Caroline but failed as he couldn't go out in the sun. Stefan later found his body and realized what Damon had done.
In the present day, it seems unsure whether anyone knows of Zach's death besides Stefan, Damon, and Elena Gilbert. Damon told The Founder's Council that Zach had gone away and he continued to supply the Council with Zach's vervain, taking over Zach's responsibilities with the council.
