Although Guillermo finally fulfils his life-long dream of becoming a vampire after Derek turns him, he ultimately decides that killing humans and drinking blood isn't for him. Fair enough.

Realising that his former familiar isn't cut out to be a creature of the night, Nandor restores Guillermo's humanity in the season-five finale by putting a stake through Derek's heart. But don't fret, Derek is brought back to life by the necromancer. As a zombie. So, kind of alive.

Season 6 will premiere in 2024!
