Clockwork: I feared that this would happen someday...
- Much like the original show's episode "The Ultimate Enemy", this is considered to be the darkest episode of The Two Phantoms.
- Unlike in the original series, this is the first time that a character's death happened in the series, with Danny dying and permanently becoming a ghost (no longer being able to turn human or ghost at will).
