While waiting for the camp council to start, Lou Ellen from the Hecate Cabin was playing "got-your-nose", except that Lou really had magically disconnected Miranda's nose from her face and she was trying to get it back. Thankfully, Chiron requested that Lou will give Miranda's nose back. During the camp council, Miranda is the counselor for the Demeter cabin, with no mention of what happened to Katie Gardner or how Miranda is the new head of her cabin.
- Chlorokinesis: The ability to control, manipulate, and create plants. The children of Demeter helped in the Battle of Manhattan and use it to make their cabin look good.
- She is a natural cook as shown in The Last Olympian.
- While no explanation is given about how Miranda is the head counselor for her cabin, it can be assumed that Katie is not a year-rounder and only stays during the Summer.
- Her last name "Gardiner" probably has to do with the fact that she is the daughter of the agricultural goddess, Demeter.
