Vlad failing to save Marina and being forced to drink her blood to save their son. He knows he's dooming himself and is at an inch from breaking their vow, but Ingeras is just so important to him he's willing to become a complete vampire to save him. Then, there's his Heroic Sacrifice / Suicide by Sunlight to stop the rogue vampires from targeting him. He survives but wow, Papa Wolf indeed!
Despite now being killers, the death of some of the vampires is this as Dracula clears the stormclouds. The Governess falls to her knees screaming, Captain Petru attempts to flee the light, only to disintegrate and one of the women tries to comfort Ingeras's friend as they both burn.
