What Was She Doing Behind a Video Game, Anyway?

What perplexes me about things like this is what they're supposed to prove. Why was the Virgin Mary hiding behind a video game? Was she waiting to be found, and what was supposed to happen then? What would have happened if Mr. Rivera hadn't moved the game and she'd just stayed back there in the dark? And why does the newscaster keep mispronouncing Mr. Rivera's name as "Riviera"? There are some things which I guess Man was not meant to know.
