Could things finally be looking up for the Gallaghers? They’ve always scraped by, but the new season finds some of them getting a leg up. Picking up a month after last year’s season finale, we find Frank (William H. Macy) declaring war on the family after awakening from a coma to learn that his loved ones tossed him in the river. But Fiona (Emmy Rossum) is too busy improving her own life to worry about Frank’s. Although she ended Season 6 with a devastating betrayal, she has moved on, a warrior, and nothing is getting in the way of her new life as manager of Patsy’s – including her family. Gallagher golden boy Lip (Jeremy Allen White) finishes up his time in rehab and emerges with a new outlook on alcoholism and a grim vision of his future, whereas the once-unstable Ian (Cameron Monaghan) now is thriving as an EMT and in a comfortable relationship. Debbie (Emma Kennedy) is still figuring out how to be a good mom to young Franny, while Carl (Ethan Cutkosky) has some big decisions to face as he enters manhood. With Fiona’s new determination to make something of herself, will the rest of the Gallaghers fall apart without her there to pick up the pieces?
