‘Gotham’ Season 3 Spoilers: Why Was Poison Ivy Recast? Plot Description Reveals Big Change

Poison Ivy is all grown up in “Gotham” Season 3, and she will be played by “All My Children” star Maggie Geha.

For the first two seasons of “Gotham,” Poison Ivy (Clare Foley) was just a young girl the same age as Bruce Wayne (David Mazouz) and Selina Kyle (Camren Bicondova). Fans assumed there will be a time jump in the upcoming season of “Gotham,” which would explain the character’s grown-up version. But according to Entertainment Weekly, there’s no time jump. The synopsis explains her transition: “The series also will catch up with the future POISON IVY (Maggie Geha), who, after an encounter with a monster from Indian Hill, finds herself reborn as a young woman who’s harnessed the full power of her charms.”

Executive producers Ken Woodruff and John Stephens also explained to TV Guide that it was essential for them to transform Ivy from a young girl into a sexy and manipulative woman.

"Canonically, Ivy is a character who makes use of her seductive powers to get what she wants in the world," Stephens said. "Transforming Ivy early in the season allowed us to play to a lot of those abilities that Ivy has, while playing the fun of someone trapped in a body that isn't theirs."

Woodruff added that Ivy’s transformation is not just physical. "There is a deeper, more emotional character side of [the transformation]. We took Ivy from the 15 year old socially odd girl, to someone who is a little bit darker, who is maybe willing to do things and harm people," he said.

Ivy “Pamela” Pepper was first introduced in the “Gotham” Season 1 pilot as the daughter of Mario and Alice Pepper. Mario was a “mean” father who was used as a scapegoat suspect for the murder of Bruce’s parents. After Mario was gunned down by cops, Alice committed suicide, therefore leaving Ivy an orphan.

She became Selina’s friend and they even lived in Barbara Kean's (Erin Richards) apartment temporarily.

In Season 2, she was employed by Butch Gilzean's nephew Sonny Gilzean to grow his “magic mushrooms,” and she was the one who provided Bruce and Selina with a plant that can put anyone to sleep.

She was last seen in the episode “Wrath of the Villains: A Legion of Horribles.” She encounters Bruce and expressed surprise that he was living at Wayne Manor again.

“Gotham” will return on Monday, Sept. 19 at 8 p.m. on Fox.
