Hey Mike,
 
Your post reminded me of what happened the day after Easter.  Normally, the Pope would go to Castile Gandolfo and rest.  However, Pope Benedict was there.  So, Pope Francis went down, as you mentioned, and visited Peter's grave site.  When Pope Francis came back up, he released a heavy sigh or something and then quoted three of Peter the Apostle's most famous Bible sayings.  One of the cardinal's with him said, "We believe the spirit of Peter entered Pope Francis at that time."  Interesting thing to say.  St. Malachy's prophecy called for Peter the Roman to be the final pope who would defect.
