Cameron Monaghan, who portrays Ian Gallagher on Shameless, has revealed that the next episode of the show will be his last. The Showtime series, adapted from the U.K. comedy-drama of the same name, is currently airing its ninth season. And Monagahn isn't the only one exiting the acclaimed show: this news comes on the heels of star Emmy Rossum's own announcement that she will be exiting the series at the end of the season.

Monaghan, who has been acting since he was a child, landed his first starring role playing Ian, one of the middle children of the Gallagher family who, along with their neighbors in a low-income neighborhood in Chicago's South Side, struggle to get by in a changing landscape. Gallagher's character has faced a lot of hardship on the show, from coming out to his family to dealing with his bipolar disorder. The actor has received recognition for playing the character, especially for the relationship between Ian and Mickey, his first boyfriend, but now he feels that it's time to go.

Monaghan shared the news on Instagram in a long caption accompanying images of himself and some of his castmates, including Ethan Cutkosky (Carl Gallagher), Jeremy Allen White (Lip Gallagher), Steve Howey (Kevin "Kev" Ball), and Shanola Hampton (Veronica "V" Fisher). In his statement, Monaghan explains that he has known that he would be leaving the show for a year, but kept it a secret, wanting viewers to be surprised and to "experience Ian's unsure journey with his character."

Monaghan recalls how he began filming when he was 15, and how much he has grown in the nearly 10 years since. He notes that he is "gracious" for everything the experience brought him, especially the people he met on the show. "All good things must come to an end," he proclaims, noting the cliche. He ends his statement by thanking the fans for watching and signing off with a question about the future: "Goodbye, Ian Clayton Gallagher. We’ll meet again?"

Though it's sad to see Monaghan go, it does free up his schedule for his other notable TV role(s). Monaghan recurs on Gotham as twin brothers Jerome and Jeremiah Valeska, who bear a resemblance to Batman's nemesis, the Joker. From the beginning, the show has teased that Jerome could be the Joker, but neither he nor Jeremiah has ever been officially given the moniker. As the show prepares to enter its final season, word has spread that there's yet another Joker on the horizon, and this one might be the real deal. Audiences will find out when Gotham season 5 five premieres early next year.
