When Mike gives Fredo *the kiss* was that a signal to his bodyguard to take Fredo out? (I believe he still thinks his bodyguard is alive). But then again I don’t think Mike wants Fredo dead at that point.

Or was it his way of letting Fredo know that he knows and he just wants to frighten him.

Or was it just an outpouring of emotion. The way he grabs his head afterward is quite emotional.

Or was it just some classic Catholic imagery.

Or all of the above.
