TOTD you are right - I read this
Carried by inertia, the airplane continued to climb. A flight attendant called onto the intercom, apparently in response to Robert, who may unintentionally have rung her while trying to rouse the captain. She said, “Hello?” As if the buffet weren’t enough of an indication, the stall warning erupted again, alternating between STALL STALL STALL and a chirping sound. The warnings sounded continuously for the next 54 seconds.
The flight attendant said, “Yes?”
Robert ignored her. He may have realized that they had stalled, but he did not say, “We’ve stalled.” To Bonin he said, “Especially try to touch the lateral controls as little as possible.” This is a minor part of stall recovery, and nothing compared with lowering the nose.
and clearly thought to myself no trained pilot could miss those cues - evidently I was wrong!
