I love the contrasting approach of Daryl and Carol.
Daryl just refuses to adapt to Alexandria's look and way of life. He's very guarded and suspicious, and everyone can see that.
Carol, on the other hand, appears to love Alexandria. She immediately changed into this preppy Brady Bunch Stepford Wives look, and she appears to embrace Alexandria the most. But then, during psych interview, she flat out lies! Just goes to show that her plan is to infiltrate Alexandria and her loyalty is still with Rick. Awesome!
