A couple of days ago, Dex and Cal would talk for hours and hours, admiring eachothers intelligence, but then suddenly, It's like Dexter has murdered Callums family or something

I reckon after he found out Charlie nominated him, something just clicked in his head, and it's like, now he will do anything to get at Dexter, like for example, Callum is now claiming that Gina, the one that trusts Dexter the most, is one of the only 2 housemates he trusts completely, along with Sam, and that them 2 are his "triangle".

He's also filling Gina up with his bull****, like he has done with Sam since day 1. He's manipulating the two with his lies...
