Sylvia followed Dinah and soon found the crack, hiding a door within the windmill. She whispered to Dinah proudly, "Nice find, Dinah!" She wanted to investigate immediately, but she remembered Aisha's and Yorik's words. This technically wasn't their investigation. It was Yorik's. She looked around to see if Syfr was anywhere nearby. 

If Shortfang's familiar could be seen, she would wave to the owl and try to signal that she found something. If not, then she would head back to get Yorik and her friends. Once she reaches the group, she calls to them, "Yorik! Guys! Dinah and I found something! Follow me!" After telling them such, she would lead them back to where Dinah found the crack.
