Lost Girl returns this Sunday with a two-part premiere that kicks off the show’s fifth season ± which will also be its last.

With that in mind, star Anna Silk tells ET Canada that fans will get “all” the answers they’ve been waiting for — just maybe not right away.

“Season five certainly starts with a bang,” admits Anna, who plays supernatural succubus Bo on the series. “It’s really hard to talk about without giving too much away but I can tell you there are some new players in town.”

In addition, she adds that fans are “going to see our core group — the gang — with some interesting dynamics,” she says. “Some of those relationships changing a little bit.”

Meanwhile, Anna’s costar, Rachel Skarsten, says that what’s always excited her about Lost Girl has been the show’s strong female characters. “I’ve never been a part of a show where the female characters drove the stories” she says. “It’s been so much to have women of all ages come up to me and say, ‘Wow, you’re so kickass!’
