@ckvghduser: it's easy to explain: 2 mods who normally do not or hardly ever vote will vote because it's Aria, so that's 2 votes. Plus there are 4 new voters in this challenge, who may or may not have been alerted to this challenge by Aria fans.
It all comes down to the voter base probably not being very representative and the chance of the voters for a specific girl being online.
But who knows, perhaps another day Lorena will still beat Aria, and let's not forget that for the same reasons Aria got beaten by Bijou ;-)
@eggytrump: you get to choose a new girl to challenge Mirka starting at 12:00 paris time!
