This newbie thread was a good idea. I stumbled upon this site, and very helpful answering questions I had.
So here is my "newbie" question/opinion.
It has to do when Michael and Enzo are on the steps outside, ready to protect Vito.
When Mike is talking to Enzo, and right after lighting the cigarette, Mike seems to have an odd look, as he looks at Enzo. I think I read on here, it was because Mike thought Enzo was so nervous, yet Mike was under control.
I always thought it had to do with Mike thinking something was up, or something coming to him that Enzo is hiding something. That scene didnt sit right with me, for some reason. Or am I reading too much into it? Just seems Mike is thinking something there about Enzo.
