Flashback is a character who only appeared in Birthday Girl Down. He was at Henry Hart's house with Charlotte, Jasper, and Henry, and was invited by the latter to come over to his house for the first time. He and his friends were studying the Periodic Table, using their PearPads. Later, he would retell the story of Debbie Putch's disastrous birthday one year ago in a flashback sequence, hence his name.
- Flashback is one of the show's most lesser-known characters, having only received a few minutes of screen time. Even minor characters like Carlos have more screen time.
