卡梅隆莫納漢在 Instagram 發表退出感言，表示自己在劇中擔任近十年的固定班底，當時拍攝試播集時年僅 15 歲，對於能與這部劇一同成長感到相當幸運。過程中認識許多好友、家人以及最棒的同事們，這是一名非常幸運的演員才能夢寐以求的。
I have been a series regular on this show for roughly ten years. I was the tender age of fifteen when we shot the pilot, and I came of age in so many ways, both legally and personally. I was very lucky to mature and grow with this show. Experiencing so many firsts, maturing as an actor, a professional, and a human. In the process gaining friends, family, and the best coworkers a very lucky actor could ask for, and for this I can be nothing but gracious. All good things come to an end. An old cliche, but one that rings true with a sincerity and clarity especially in moments like these. Everything ends. The next episode will be my last. I have known since last year, but I didn’t want to give it away too early as I wanted this season to be a surprise for the audience, allowing them to experience Ian’s unsure journey with his character. This role has been a joy to inhabit, a wild and special ride, and I’d like to thank #Shameless as well as you, the viewers, for being there with him. Goodbye, Ian Clayton Gallagher. We’ll meet again?
