At first I had my doubt about Yamato being a spy for root in ANBU, but after the encouter with Kakashi that doubt vanished. I just had that feeling. He could have easily been a team member once, or his subordinate as he says senpai to Kakashi.
Just as Tsunade said, Danzou is a cold, calculating strategist. He came in, asked about Tsunade's choice for the leader, and then left. Then there's the previous episode, where she was confused about why Danzou would only select 1 teammate when he could select 2.

Also, Yamato showed up late to the hospital right after the scene with Sai and the masked guy.
