Carley has been trying to warm up to Daniel because she knows that it would be best for their family, but I think when she helped Daniel with his basketball, she finally got a glimpse of the "real Daniel". Daniel trusted her with a secret about his dad- that Mr. Murphy wants Daniel to play baseball, but Daniel wants to play basketball and he feels like his father is disappointed in him- and that made Carley realize that the Murphys are not perfect.
