Yeah, Sarah expected this. It's not like she can blame Cosima for her reaction, either. "I know how weird this is," she says, like there aren't a thousand stranger things happening around them, "but it's not her fault—the way she is. She's trying to be good. She saved my life." It's practically impossible to summarize the change in Sarah and Helena's relationship, so Sarah just leaves it at that. "She won't hurt you."
