Poison Ivy (Maggie Geha) is all grown up in “Gotham” Season 3, and the young girl who has a keen affinity with plants is suddenly thrust into adulthood.

But strangely enough, Ivy enjoys being grown up. “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 told Comic Book.

On the other hand, Ivy’s friend Selina Kyle (Carmen Bicondova) won’t like the change a single bit. “The roles will change, from Ivy’s perspective – it’s not that Selina looked down on Ivy, but Selina’s older than her; she feels this older sister connection to Ivy,” Bicondova explained to Variety. “So when the new Ivy arrives, she’s older than Selina, and I don’t think it’s going to go well for Selina.”

Selina might get even more upset if Ivy starts driving a wedge between her and Bruce Wayne (David Mazouz). Mazouz told Den of Geek that he will have some upcoming scenes with the grown-up Ivy, and it has been speculated that their new dynamics would upset Selina.

Will Ivy make a move on Bruce and make Selina jealous? How will Bruce react to Ivy's transformation?

Aside from Ivy, Bruce will also share some scenes with Oswald Cobblepot (Robin Lord Taylor), better known as The Penguin. “I remember thinking that's the first time I've seen him waddle in person,” said Mazouz.

The actor failed to say whether or not these interactions with Ivy and Penguin would be caused by the original Bruce or his doppelgänger. Despite originally feeling sorry for his double, Mazouz said that jealousy would arise from Bruce after finding out that his double went on a date with Selina — which is something he’s failed to do since the very beginning. As for his clone, he would continuously be jealous of Bruce’s wealth and privilege.
