Exactly....if Daniel has a gazillion times more Methadone in his system than is prescribed....Howieanna will blame Anna. She was out of it and gave him too much. I can just hear him now....the lying scum.
Some hospitals have cameras to view the patients which sit at the nurses station. There are about 4 little black and white monitors each of which looks at a patient for about a minute and then switches to another patient.
If there were a camera, it would've been focused directly on Anna and her bed. So whatever Howard did he'd have to have done across the room from Anna. And if Howard suspected a camera he'd have done it discreetly away from there.
