Yes, I thought he was probably answering a little more vaguely than Kurtz anticipated. He probably said a big hmmm after watching the deposition video.
I think he was helpful to the defense. He came across honest and sympathetic and he's the only person who was around BC in the days after her death that can attest to how he was acting. And I think that the way he spoke, in a calm and measured way, was probably soothing to the jury following the craziness of BZ v. BL. He seemed to have no biases and may be the most trustworthy witness we have seen so far.
