Edward had just saved Bella from these weird men with horrible thoughts, the men had just harassed Bella. He swerves onto the street pissed off

Edward: "I should turn around in rip their heads off." he says upset and angry

Bella shakes her head, still trying to process what just happened "I don't think you should.."

Edward: he glances at Bella then back at the road "You don't know the vile things they were thinking."

Bella: "And you do?" she blurts out, not aware of the fact Edward's a vampire yet nor the fact he can read minds..but not hers..
