Yeah... still, I wouldn't hold it against Zii for a few reasons mentioned already (being drunk, Gary being Gary, DiDi being DiDi, her basically doing both of them a favor, whatever)
But Gary's not around so not much use in crying over spilt milk or however the saying goes.
Anyway, apparently... Sonja's logic beats alcohol corrupted Zii's reasoning. I guess we'll have to see how Eric reacts, if he ever finds out. (I feel like Zii is going to be honest about it, though. Unless she chickens out and is too emberassed to ever contact him again)
