Though the sun briefly deters him, Dracula's far from dead. Quincy and Renfield find him to still be an incredibly intimidating figure, and one who's still capable of levitating up into the air while grabbing the neck of mere mortal human Quincy. This is the moment where all hope looks especially lost, considering Renfield is collapsed on the ground, having succumbed to the various wounds he's incurred during the battle. Quincy's arms are just free enough to stab Dracula in the foot, a move that the vicious vampire initially laughs off as being a foolhardy attempt to save her life. However, this maneuver isn't meant to instantly kill Dracula or free Quincy. 

Instead, it forces some blood out of Dracula's now-injured foot, where it can now drop onto Renfield and heal him. Quincy's plan ends up working like a charm, with that mystical blood reviving our hero, who promptly saves Quincy from the clutches of Dracula. The two confront each other and Renfield reaffirms what he heard in group meetings for people in abusive scenarios: victims in toxic relationships are the ones with all the power. After violently hammering this point home to Dracula, Quincy proceeds to trap the vampire in a spiritual containment field (which she learned to conjure up through "a wiccan Tumblr"). After so much bloodshed, Renfield has asserted his dominance over his old boss, and Dracula's finally been stopped in his tracks.
