I have a question is anyone else suspecious of Tessio's involvement at the hospital. His men are guarding the Don, but disappear; presumibly detained by the Cops. But they could have just as well left if he decided to make a "smart move" and betray the Don to get more power. Don't get me wrong, I think Tessio was still loyal to Vito and only really had a problem with Michael and thought he was a crappy Don when he decided to betray him.

But if I am wrong that could mean that Tessio is a real rat. What do you guys think?
