Long time lurker here! Correct me if I am wrong but doesn't Aubree have Chelsea's last name? At the end of Chelsea's 16 and pregnant,Randy, Chelsea and some other girl are in a lawyer's office and I am almost positive it had to do with a name change or adding Chelsea's last name. This all over after the infamous texts from Adam. I tried to go back and find the episode but am having trouble, does anyone else remembered??
