Jenna Dewan as Bailey Nune – Confirmed to Return!
Jenna Dewan is expected to return!
In June 2025, she posted that she was in Prague on her Instagram Stories, writing, “Starting Season 8 off in the most amazing way.”
While on Jimmy Kimmel Live this summer, Nathan confirmed the season kicks off in Prague, saying, “We went off to Prague to shoot a portion of the premiere episode of season 8..It felt like I was shooting Casino Royale. I’m telling you, I’m in a suit, you’re walking down these incredible streets. I love the history. There’s so much history. This building was built in the 1400s, but behind it are the old buildings. This beautiful clock, and it’s such a dark history, too. This beautiful clock, it was so incredible, they said after the fella made it, they went and burned out his eyes with a white-hot poker so he would never make anything so beautiful again. Like, these were tough times.”
