Stefan settled down beneath her and continued to listen. If Rebekah and Klaus had a vampire working for them and Klaus hadn't turned off his humanity ... it didn't make sense. Stefan thought about it as he stroked Elena's hair. Klaus would turn off his humanity to avoid a flip. "Or it was a trap," Stefan said, not trusting of this vampire that Elena had run into. Elena turned slightly so her eyes were on Stefan as he shook his head.
"Klaus would turn it off to avoid that. He's capable of it, he wouldn't waste any time doing so. Did you tell him anything?" Stefan asked, getting more and more suspicious of this vampire. Would Klaus really be that sloppy? Maybe. There were so many vampires they were turning, so many people they were killing and so many that they were using, was it hard to keep count of it all?
The guilt of not being out there right now, saving people was heavy on his chest, but Stefan knew that he did try. All the time, everyday. Elena and Stefan couldn't save them all, but they did try, little by little. He knew it bothered Elena, bothered her more than she liked to admit, it was just apparent. That's who she was.
