Frankenstein had a relapse and found himself back in rehab. Dracula discovered him passed out in the bathtub at his apartment. His concern grew after a week of calling with no answer or returned messages and he went looking for his troubled friend. (That hide-a-key really did come in handy.)

The bride was finished. She chose herself.
Either way, whether Frankenstein was to be reformed or remain a junkie she would be gone. He lost her and would be alone.

And that made him sad.
