Eliza Dushku's character was a bit of a dud, considering she was introduced so late in the show, with only 4 episodes left--they should've introduced her during the premiere episode of Season 4. Also, didn't like what they did to Rebecca, but those demonic cult serial killers seem out of whack, even with this show.
The short episode order is taking its toll in the show's pacing, with all these new characters being introduced and the main cast having fewer scenes--Hood spent the entire episode in a jail cell, and Sugar doesn't even appear in the episode; even more puzzling is Ryann Shane, who's always billed in each episode and never appears, LOL. Hope they make up for it during the last half of the season.
