Season 5 | Episode 10 | “South Side Rules” | Aired Mar 22, 2015

Throughout this season of Shameless, as Ian has come to terms with his bipolar disorder diagnosis, we’ve learned that the disease is a series of highs and lows. The same explanation could be used to describe the experience of watching Shameless, and in particular, Mickey and Ian’s relationship. “South Side Rules” epitomizes this idea with some of the most heartwarming moments we’ve seen all season (maybe ever?), followed by devastating revelations.

Ian and Mickey have been struggling to connect all season. Ian’s mental illness, and his refusal to acknowledge it, have put understandable strain on the couple. They are finally able to be together openly and honestly, but have found the road to be just as bumpy on this side of the closet door. Mickey has risen to the occasion and has been there for Ian through it all, but Ian hasn’t made it easy to support him. Despite Ian’s protestations, Mickey has—but for a momentary crisis of faith—remained steadfast in his commitment to taking care of him.

As enjoyable as it’s been to watch Mickey morph into a capable and loving partner, Ian hasn’t exactly appreciated the attentiveness. In fact, he’s got all this pent-up rage at his boyfriend for treating him like a patient instead of a partner. He doesn’t want to be handled by a nurse with kid gloves; he wants to be handled by his tough-guy boyfriend with tattooed knuckles. Ian knows just what to say to bring out the fighter in Mickey, so he picks a battle and gets the reaction he’s looking for. The two boys go at it, throwing punches and rolling around in the dirt. They finally relax, breathing deep and deeply satisfied. It may not be the most recommended method of communication, but it is their way and it works.

It only makes things sweeter that this major moment takes place at such an iconic “Gallavich” location, complete with shotgunned beers and pullups.

Once the fight is over, Mickey backs off and allows Ian to drink the beer he wanted. They kiss and make up, and it feels like they are in sync for the first time in a long time. Drunk and elated, they return home, singing “Love is a Battlefield” (ain’t that the truth) loudly in the street. Ian suddenly realizes they’ve never been on an actual date, and decides they must rectify that immediately. They head inside to change so they can take each other out to a real sit-down dinner, when they are ambushed. Sammi has called the Army to come get Ian, who’s been on the run for going AWOL (among other things). Military police swarm in, grabbing Ian and fending off Mickey with guns.

The swing is severe. From the highest high to the lowest low.

Mickey and Ian aren’t the only couple to swing the pendulum from exhilarating to horrifying in “South Side Rules.” Debbie and Derek were so sweet a few episodes ago. When they first kissed, I leaped for joy. It felt, for a fleeting moment in time, that this relationship was exactly what Debbie needed; someone age-appropriate and legitimately into her. Even the idea of them having sex, as upsetting as it is, seemed at least better than the situation she had with Matty. Debbie even had Fiona take her to Planned Parenthood so she could behave like a responsible sexually active teenager. But then she had to get it into her head that getting pregnant was actually a desirable thing to do. She had to orchestrate a situation and blatantly lie to Derek to try to get pregnant on purpose. Now this adorable story with loads of potential is a total disaster. Absolutely nothing good can come of this except for Debbie getting supremely lucky, not getting pregnant, and coming to her senses before the next time they have sex. Chances of that happening on Shameless? Slim. All signs point to this low sinking even lower.

Week after week, Shameless continues to balance these stunningly beautiful moments with scenes that make you feel like your heart is being ripped out and trampled on. It’s not so much the what as the how. Ian being apprehended by MPs is not entirely shocking, but to have it happen because Sammi tipped them off in an act of revenge is brutal. The notion that Debbie could get pregnant is also not impossible to believe as she and Derek become more serious. But to have it happen on purpose, to make it something Debbie intended to do, makes it much more difficult to swallow.

Shameless airs Sundays at 9/8C on Showtime.
