I have the feeling you are correct. I'm guessing hubby is in a hurry for two reasons: his ladyfriend and the fear of what Terry'd reveal if she regained speech.
Especially since the concubine would lose the house she is in since Terri's money provided it.
Everything the concubine has, 1/2 of it belongs to Terri. Even more if it is proven that HINO abandon her and tried to kill her (he is trying to kill her).
So, people should look at the basic facts. Look what HINO and the concubine have to lose or gain by Terri living or dying.
The tramp had no business having those kids. She deserves everything she gets. God forbid something happens to one of those poor kids and HINO decides their fate.
