After five supernatural seasons, Lost Girl will come to a sure-to-be-explosive conclusion in the series finale this Sunday, and star Anna Silk sits down with ET Canada’s Sangita Patel to reveal the finale will be satisfying for fans — who should also prepare to shed a few tears.

Reading the script for the final episode, says Anna, was emotional. “It took me like five days to get up the courage to read it because I was just so emotional about it,” she says, “but when I read it, it was just like reading the end of the greatest book.”

As Anna explains, Lost Girl was more than just a job. “I’ve made lifelong friendships from it and learned a lot from Bo,” she says of her character. “Bo was a kickass female role model so she inspired me.”
