I remember reading a while back episodes are being shown out of order. I'm not sure why they are doing this, but if I had to hazard a guess I'd say it was to push the buddy-cop aspect. For the first couple of episodes, I wasn't really feeling the vibe between Ealy and Urban, but that has improved, which makes sense if the episodes are being shown out of order. It's like they jumped from being reluctant partners to buddy-buddy with no story in between.
I think showing the episodes out of order is hurting the show's ability to have an overarching storyline because everything is all over the place.
