'When Calls the Heart's Pascale Hutton and Kavan Smith react to their characters becoming parents! On episode 10 of season 9, Rosemary Coulter discovers she's pregnant. However, because of her struggles in the past, she's not entirely convinced she's expecting, so for now, she's keeping the news to herself and isn't telling her husband, Lee Coulter. Hutton and Smith, who have been strongly campaigning for this onscreen milestone, open up to ET's Deidre Behar about their wish finally coming true. Smith praises Hutton for being relentless in her quest to see this storyline through. Hutton says she played a big role in the creative direction of her character, and sheds insight into many of Rosemary's choices. She also shares what it was like filming those emotional scenes with Andrea Brooks (Dr. Faith Carter) and Erin Krakow (Elizabeth Thornton). Smith teases when fans can expect Rosemary to tell Lee the big news and how he'll react. 'When Calls the Heart' airs Sundays at 8 p.m. ET/PT on Hallmark Channel.
