The basic Red Court statblock in 'What Goes Bump' includes Echoes of the Beast (bat, I guess?) -- but the specific RCV statblocks in 'Who's Who' (Bianca St. Claire, Ortega etc.) don't have it.
So should RCVs have it or not? I don't really see the need personally -- they're not as bat-like as werewolves, say, are wolf-like. (But I wouldn't have given it to Goblins either, so maybe I don't really 'get' the idea behind who gets it...)
