Here's some scoop on Bates Motel from this week's (Posted on 2/28/17) Ask Ausiello column.
Question: How long will we have to wait before seeing Norman in full-tilt-Norma mode on Bates Motel? —Andrew
Ausiello: We got a little taste of it this week. And per EP Kerry Ehrin, there’s a “substantial amount” of Norman-as-Norma still to come. Speaking of which, how did she react upon seeing Freddie Highmore all decked out in wig and heels the first time? “It was a sheer delight,” she enthuses. “He looked so good and [channeled her] so perfectly literally every time. And when that shot [in the trailer] comes up of him in the wig, I just laugh. I just love it so much. It makes me so happy.”
