Alien Blood: While Sabrina has a piece of the Void inside her, her blood is as white as the emptyness of the void. After she purges the Void, her blood goes back to her natural red, but then it's too late.
And I Must Scream: Blackwood can't be killed, yes… but there's nothing stopping Prudence from chopping him up with a chainsaw and scattering his pieces to the four winds.
Body Backup Drive: Sabrina Spellman's soul is dragged by Hilda, Zelda, Ambrose and Nick to the dead Sabrina Morningstar's body after Hilda, Zelda, Ambrose, Nick, Prudence and Agatha find out the former went alone to defeat the Void. Unfortunately that also means Sabrina has a piece of the Void inside her.
The Hero Dies: Sabrina Morningstar dies after escaping the Endless, living just long enough to warn the others of the coming of the Void; and Sabrina Spellman dies while sealing the Void: first, her body is left behind inside the Void when her soul is pulled out to Morningstar's body; then, her soul in the latter body is bloodletted.
Heroic Sacrifice: Sabrina sacrifices her life in the bloodletting for that of her trapped friends and the trapping of the Void.
Patricide: Prudence kills her father, Blackwood, for having lured in the Eldritch Terrors as part of his power plot.
Public Domain Artifact: Pandora's Box, which, unlike in most versions of this trope, is empty and it is Sabrina who will fill it with the Void.
Senseless Sacrifice: Averted with Blackwood, who was about to sacrifice Sabrina for her (rather small and powerless for his desires) piece of the Void.
Together in Death: At the end of the episode, Nick Scratch reveals he drowned himself swimming in the Sea of Sorrows, and is reunited with Sabrina in "The Sweet Hereafter".
Traveling Salesman: The Trinket salesman from whom Father Blackwood stole the Perverse returns in order to exchange the Endless for the empty Pandora's Box.
Unrealistic Black Hole: Sabrina Spellman's soul becomes one since she was teleported away before being able to completely store the Void in Pandora's Box, so she has a piece of the Void inside herself. This results in things spontaneously disappearing at first, such as Sabrina's birthday cake, and later people get absorbed to the Void when Sabrina loses control of her emotions or in self-defense. Ambrose, Harvey, and Nick venture into the Void to rescue Prudence, Roz, Mr. Kinkle and the miners while Robin and Theo hold the rope.
