Whoa! I was under the impression Ron got custody because he had a job and Crystal didn't. If you are referring to her drug problems, he has a long arrest record for that as well as other mischief.
Ron did not bring them back after a weekend's visitation and then filed for temporary custody. Crystal didn't receive the notification of the court date because he gave the court an incorrect address, and she missed the court hearing, and he planned it that way. Little tricks like that should not have gone unnoticed by that judge!
I believe Crystal loves the kids as much as Ron does. Let's not be too quick to judge the other side. He is not a saint.... any 25-year old "man" who is living with a teenager is not perfect, and should not receive a pass. Playing house is not an ideal situation to raise two kids in!
Here are the court papers for the custody hearing. Document 2 is the initial filing bio mom made to try and get the kids back. Document 1 is the hearing and decision of the judge.

Edited to Add: These documents are very telling about why the Bio mom lost custody.
