A man who drank alot of alcohol would be passed out by 11PM. And I find it unusual, that a man would walk out of a burning trailer, deposit his GF outside, and run back in for children. A more likely scenario would be that both parents searched for children in the trailer before exiting out the rear door.
But, that is my opinion. FWIW.
And not to be mean, but there is no way he carried her out of there.
