How did we not know that The Visitor was Geno?

I mean, let's think about it. If anyone would have listened carefully enough, at least someone could tell that was Geno. But going over guessing, someone could have searched on the internet and noticed the Visitor has the same voice actor as Geno. And Fortnite wouldn't use the same voice actor for important characters.

So how did we not see it? How did the Order not notice? Her of all people! Her of all other members of the Seven! How?
