Lucy Lawless will reprise her Battlestar Galactica role as D'Anna Biers, a Cylon posing as an investigative journalist, in a 10-episode arc during Season 3, which begins production in April. That sound you hear is countless Sci Fi Channel fans doing the Xena yell.
10 episodes is a lot though. Looks like she is going to play a big part. Wonder if it will be interacting with the crew or behind the scenes Cylon wackiness like on Capirca.
