Ok I know I haven't been here in a while but I'm not giving up on this couple/ friendship. Ryan has an effect on Calliegh that makes her think outside her box and makes her realize that not only is it ok but that she doesn't always have to be right on her theories. She also doesn't have the same rough edge that she does when she interrogates a suspect when they hold an interrogaton together. The chemistry between thw two can stay at the friendship level and work but it could also got up to the romantic level. It depends on if tptb will play on it.
