So giving the benifit of doubt here,
Was Alex under the control of her "Pimp" during her stay at the Dr. Phil House and at the rehab centre ? I don't remember if that was addressed. Pimps are much like abusive husbands, they control through fear and intimidation, and generally the girls are much younger, easier to brainwash them with promises of money, and the "Glamorous Life ". If the girls are assaulted by their Pimp or their John, what recourse do they really have ? Press charges, sure and they get charged with soliciting, it a vicious life. Oh, and her "BOYFRIEND" that she was in "LOVE" with, was probably her pimp, it isn't uncommon . Was she or her family being threatened if she didn't comply with running away with him, Alex was definitly hiding SOMETHING from the Doc and everyone else, at this point nothing short of chaining her to the wall though will keep her from running away, that was my impression anyway, I also had the impression near the end, she was already trying to figure out a way to run BEFORE she had to go away again, the wheels were turning.
As for Mom, okay you ran to ENZA, remember the woman you hated the last time, threatening to sue the show because there was no miricle cure ? I'm not the eternal optimist the Doc is, it took fifteen years for the girl to get this way, it won't happen overnight, no matter how much "Commado Parenting" you do, look you can't decide after fourteen years of the child raising herself, that suddenly you want to parent and the child will happily comply with your wishes (can I get an AMEN from parents of teens) hell, even parenting them from BIRTH, teens are not known for their happy compliance with rules being foisted on them. The big thing is, you did NOT earn her RESPECT and TRUST as a child, so now at fifteen she's not going to suddenly wake up and say, "Oh Mom, I've suddenly discovered that I will just give you my everlasting trust and respect from now on ", it dosen't work that way, so what now ? If this opportunity dosen't give you the "MIRICLE" you are seeking, will you hire a lawyer at that point ? Or maybe will you take a harder look at yourself ? I didn't really get an impression of Mom doing much to further the situation, did she quit drinking all together ? I'm not sure that was adressed.
I do hope that this opportunity isn't wasted on her, I really do NOT belive any kid is a hopeless cause, and one day I hope she has the chance to thank Theresa for turning her over, and getting her out of that life, even if temporarily, and in this case I really hope I eat those words.
