I just rewatched this episode, and I'm genuinely confused. What exactly did Ian do wrong? Did he force Mickey out of the closet for his own sake, or because he wanted Mickey to be able to be himself?

Ian knew how Mickey's dad would react, so why did he want him to come out? I understand wanting to be open about their relationship, but Ian also knew it wasn't safe.

Carl and Kelly had awesome chemistry. Much like Jimmy/Steve despite coming from a privileged background actually enjoyed and adapted well to the Gallaghers' dysfunctionality. She also helped push Carl to his full potential. While they did breakup due to cheating and long-distance relationship not working out, they still broke up on good terms. Unlike most Gallagher significant others who bitterly sever all ties after a traumatic breakup, she and Carl still managed to stay good friends in the end.
