Do all these doppelgangers exist in the same universe?
We already know that victorious and icarly exist in the same universe and that shelby marx and tori exist in the same universe (which also means that andre and his doppelganger harper exist in the same universe) but since stacy from zoey 101 appears in icarly and sam and cat does that mean that lola martinez and rabecca and trisha kirby (trina and sam's doppelgangers) exist in the same universe as well as carly's doppelganger? (I forgot the name of the character miranda cosgrove played in zoey 101 i think it might have been paige)
But zoey 101 is a tv show in victorious is that just a plothole?
And there's also an icarly video where victoria justice appears as herself so maybe zoey 101 is a show in this universe and she plays lola both in real life and in this universe
