Lauren gained in popularity in the episode 5. She is pretty but has a cold heart and everything she does is calculated. She threatened Syd. Even though she toned it down afterwards it is obvious as soon as Syd is annoying her in any way she will transfer her or something else very evil. She is waiting for the right moment like a spider in the net. She knows very well if she had transfered Syd to another field office all of her friends in the CIA and more important Vaughn would never forgive her. Lauren loves Vaughn but she does not deserve him.
