Yes they were. The entire thing was a scheme to get Littlefinger to over play his hand due to overconfidence, and of course he did because he thought he was in control. Sansa would have never sent Brienne away if she was afraid of Arya, but she wasn't afraid of her at all. Arya was repeatedly lying about both her own motivations and what she thought about Sansa, and Sansa of course caught onto the lies because they were obvious to anyone who knows Arya (but wouldn't be to anyone else). Sansa was also repeatedly lying to Littlefinger and leading him on. Bran provided some additional leverage to get rid of him beyond the Lysa and Jon Arryn scheme.
Sorry you didn't get this, but it is what happened. It was poorly done because the writers were going for a fake out, which I don't think worked that well.
This is completely wrong. They said there was a deleted scene where Sansa goes to Bran to find out the truth because she was genuinely actually considering having Arya imprisoned.
