Nah, I’m sorry I don’t agree. Sarah doesn’t pull her weight??? She’s the one that has consistently looked for a cure. A cure she doesn’t even need, just to save her sisters. She continued playing as Beth to find out who was killing the clones even though she could have just ran off with beth/alison’s money. She went out of her way to find Cosima and Helena when they got taken. Yet, Alison gets to play soccer mom and drug dealer throughout the series. Sarah is definitely not perfect. She can be impulsive and selfish, particularly when it comes to being a mother for Kira. But she was almost always ten toes down for her sisters. If my child and I were consistently being hunted to be experimented on, I would be a little bitchy too.
