I want to say that May 12, 2006 or a day around there when Carrie and Austin are handcuffed together and stuck in the closet while Abe searches the premises of a local club for drugs, while they are talking and moving around in different scenes you can clearly see that the handcuffs are no longer on them and then back on. When they finally get released from the closet they are clearly handcuffed back together and have to ask for the key from the clubs owner to be released from each other.
