- Ambiguous Situation: We're told Sky has "manifested in her human form". We're not told what her other form is. It's possible that her electrical abilities have developed until she became an Energy Being.

- Dying Alone: Sarah Jane ultimately died alone, as the Bannerman gang were all abroad when they heard of her death. It's suggested that she waited until they were gone, as she didn't want to trouble them. It's also implied that they didn't know she was ill given that they "got the news" rather than expected it.
