At the end, do we really want to see that what he ultimately feels he must do in order to find peace is... to throw himself out a window? We've already had tons of suicide on the show; is what really needs to happen is that the main character needs to splatter across the sidewalk for it to have closure? He's a narcissistic ad man, for crissakes, not Julius Caesar.
Frankly, in the context of the recent gang rapes of drunk girls (Steubenville, West Auckland's Roast Busters and Halifax, to name a few of the most shocking) liquor marketers should start thinking about the optics and their own fairly flimsy commitment to responsible drinking. Thus far, responsibility has generally been translated into talk of driving and personal health. But corporate social responsibility needs to extend towards perpetuating dangerous attitudes about women, too. And booze marketing is full of them, although, this, by far, is the most offensive I've ever seen.
Orphan Black is about clones and conspiracies. Part of the series' appeal is doubtless its gimmick. The twinning process -- wherein an actor plays opposite himself -- has been around for decades, but Orphan Black does it better than almost anything before. Even when the clones hand each other glasses you forget special effects are involved!
I first heard the statement, "Once a cheater always a cheater" when I was in high school. Maybe some women are born with an innate desire to believe in the ability to change. I know I'm a little more evidence-based myself and if history is any indication, I'd say Don Draper will spend the rest of his fictional life appearing in the beds of women all over 1960s Manhattan.
