I've found dozens of questions about this, but not the one I want to ask.
Bob the Rogue is killed by a Finger of Death from Darth Villainous. Joe the Cleric has the next action in the initiative order and is standing close by.
According to FoD description: "A humanoid killed by this spell rises at the start of your next turn as a Zombie."
If it isn't the start of Darth's next turn does Revivify work?
P.S. As a Bard with Secrets of Magic you could learn Contingency & Revivify, which is another flavor of this conundrum.
