When Harlot, Professor Adkinson, and Zack cause terror in the hospital, everyone is evacuated except for Pete. Sheriff Tommy gives Chelsey his pistol and tells her to be careful because she wanted to save Pete, Zack, and Professor Adkinson.Chelsey threatened Harlot, so Harlot undid her kissing spell and freed Zack and Professor Adkinson.

She begged them to keep it a secret, which they gladly agreed to. Chelsey and Zack began dating again.

In "Circus Freaks", Professor Adkinson makes Chelsey a suit and asks her to join Super Scott and become a team. Chelsey thanks the professor for the gesture but would rather live a normal life, although she says she will help Super Scott if he ever were in trouble.

In "The Dead Rose", Chelsey is watching the Channel 5 News with Zack when she realizes how Firecracker had hurt so many people. She goes to the Walsonville Hospital and begins to help by secretly healing people's injuries, such as Sheriff Tommy.

In "Silenced", Chelsey is kidnapped by the Association and procedures are being performed on her when Victoria Groves shows her to Adam Prune and tells him about her powers.
