This is right, plus in the leaked police report it said supposedly an alcoholic. This doesn't mean it was true.
It is pretty depressing being in an abusive relationship as Alison clearly was, so maybe E's depression is due to abuse as Alisons was. As usual it is inferred that the person with the mental health issues is the problem/crazy/off the rails/unreliable. Alisons husband left the kids alone while sleeping to dispose of her body, I would assume the police are combing cctv to ensure Hub was at home in bed as he says and not doing a three hour round trip. If she drank to blindness as alcoholics generally do when they fall off the wagon - she would be easy to 'manage' and not fight back.
if she drank alot it would make sense that neighbour put her bed too, that seemed really weird, now I get it.
I totally missed mention of alcohol involvement.
also explains why she didn't phone kids to say goodnight, another thing I thought really odd.
