You don't need a therapist like Ingrid to tell you that there are some serious substance abuse issues that run in the Gallagher family. During season four, Fiona served time after being arrested on two felony charges after that heartbreaking cocaine incident with Liam (who knew he'd be a boy genius by season nine?!), and she certainly didn't have the best example set for her growing up, so it's a possibility that in an effort to take control of her life, Fiona could want to take control of her drinking.
When asked about how Fiona will "respond to losing everything" when the show picks back up in January, Wells reminded us that as always, it's about family. "It's really about who we depend on when we hit our low spots: who do you turn to and who picks you up and who helps you get back up on your feet," he shared. "This show has always been about the family and how they, in their own complicated ways, step up for each other. So that's really where it goes in the second half."
Could Lip help Fiona get into the program that Professor Younes helped him get into when his drinking was out of hand? Will Debbie help pool her welding paychecks to help support her sister? Only time will tell, but we have a feeling the Shameless crew will send Rossum's character off on a positive note, and rehab or a desire to change her ways could very well be a possible ending for Fiona.
