The #1 main reason as to why I believe that Alex is Victor’s son & not Xander is this: Would there be a story for both Konstantine & Theresa going after the Kiriakis Fortune, because of a forged letter. If Alex wasn’t Victor’s son & Xander is would this story of the this whench & Zorba, the Fake Greek be written in the first place. Think about it, don’t you think it’s like putting the cart before the horse, because the both of them know that Alex has no fortune, given the Will didn’t stipulate what son had gotten 50% of The Kiriakis Fortune & they think that they can get it by way of a forged letter & that they have two characters with the same name: ALEXANDER.
