Kym, on her Youtube channel, pointed out something I had missed while watching. Brooke/Robbie receive 2 apples; Robbie eats one and Brooke feeds the horse the remaining apple. Either the producers missed it, or they didn't think it rose to the level of a violation.
Actually, I knew it immediately when I watched the show. But I don't know if it's his own apple or the apple for the horse.
