After Ivy Pepper's run-in with Fish Mooney and her gang of Indian Hill monsters in the Gotham season three premiere, things are changing for the young future member of Batman's Rogues Gallery. While she still isn't the super-powered Poison Ivy, master of all agriculture, being touched by a man whose power is to drain life and artificially age his victims had a drastic effect.

Now, she's not quite as young, growing into a full-grown woman in a young twenties body (as played now by Maggie Geha), and that means a drastic change in her character as well. Remember, this is still a fifteen-or-so year-old, just suddenly in a 22 year-old body. The exclusive featurette provided to ComicBook.com from FOX and WBTV explains a bit more about how this all happened, and what it brings to the show.

"Little Ivy has been changed, she's been morphed into big Ivy. She doesn't really know what happened to her, but she likes it," Geha said.

Producer Ken Woodruff noted that "she's going to be able to seduce" now that she's... changed.

The grown version of Ivy makes her first appearance next Monday on Gotham: Mad City "Burn the Witch." The official synopsis follows.

"Fish Mooney (guest star Jada Pinkett Smith) takes matters into her own hands to locate Hugo Strange (guest star BD Wong), forcing Gordon to reluctantly team up with journalist Valerie Vale (guest star Jamie Chung) to find her. Penguin rises in popularity after criticizing the work of the GCPD and Bruce’s investigation of the Court of Owls is compromised. Meanwhile, Ivy Pepper (Maggie Geha) is reintroduced into Gotham city in the all-new “Mad City: Burn The Witch…” episode of GOTHAM airing Monday, Sept. 26 (8:00-9:00 PM ET/PT) on FOX."
