"The answer was 'Tyler is going to be a big brother,'" Jason recalls. "He's been asking me for years. He's always wanted to be a big brother. So we played the game and he looked at Molly and I and said 'Really?' Molly made him a t-shirt that says 'Big Brother' on it and he's really proud. He wore it to school."
