Nothing they've done has really changed their lives or gained them anything except for Victor who has been Taught by Experience that scientific discovery hasn't gained him fame and fortune and won't for Dr. Jekyll either.
- Special Edition Title: The usual credit opening is replaced by a new one with Sophie Meade singing "Now I lay me down to sleep".

- Who Wants to Live Forever?: Dorian makes this speech to Lily about how life becomes empty and pointless to an immortal and eventually they become like an empty portrait of themselves. He points out that any relationship with a mortal will necessarily be a Mayfly–December Romance and that any children one has will wither and die of old age in the blink of an immortal eye. Possibly subverted, however, as he promptly calls it a "small price to pay" for immortal perfection, but it's not entirely clear whether he truly means it or if he's being dismissive to cover up his own pain; from what we've seen of him it could be either.
- Zerg Rush: The Familiars try to kill the heroes this way, and nearly succeed after losing a large amount of their forces until Ethan and Kaetenay arrive and defeat them.
