If Terri's parents were to gain custody, then they would give her the THERAPY that her two-timing-father-of-two-bastard-children-possible-BOTCHED-ATTEMPTED-MURDERER-not-legally-qualified-husband Michael was PAID FOR but DID NOT GIVE HER!!!
If Terri were to relearn how to talk, she could IMPLICATE him in possible MULTIPLE BOTCHED ATTEMPTED MURDERS of her.
Wow. Yipes.
