A big fat brain fart, I suppose. But what became of Momma Meth? You know, after they rekindled their mother/daughter relationship when Hamber needed her mommy so desperately?
Not a mention, not a passing thought, nothing since Momma flew home. We all know that Hamber is all about Hamber, that's a given. Seems to me she used Momma Meth as an emotional tampon in her "time of need," then tossed her aside like she uses other things and people, then shucks them off to the $6000 bed, just something else that's part of the hoard.
But it is weird being that they actually seemed to bond after years apart.
