It's just my opinion, but I believe Saskia and Craig are on equals when considering 2-faced-ness.
Firstly, Saskia is playing up to Maxwell's affections, poor bloke! Aswell as continuously sucking up to the group lead by Kemal and Makosi

Saskia has also held onto the Derek/Roberto comments for too long now!
As for Craig, the minute that he heard the response from the crowd, he knew that if he stuck with Vanessa, he was done for, therefore he began his transision into Team Maxkia.
Bear in mind, these are only my opinions!
