Johnny is a snake but he is also a very interesting character. Note how he tries to manipulate everybody, especially Tony, by pretending that he is angry over some minor matter (e.g. the joke about Ginny's weight, Christopher talking too much on the sitdown, Tony not handing Tony B. to Phil Leotardo but shooting him himself) so as to put everybody in his debt. When he gets what he wants, he plays it cool and says that he always wanted the peaceful solution.

Despite all these, he cannot run fast enough in the snow. Let's wait and see if Johnny will use his skills to stay out of jail.
