, I was incorrect in our PM. The in-episode
credits are correct - Julia Nickson is "Carla", (Sgt.) Ardi Maioho is "Sylvia". The IMDb is incorrect in that Carla is not "Rose's Henchwoman", Sylvia is! Conversely, Sylvia is not the street merchant, Carla is! Not sure why the IMDb added "Rose's Henchwoman" to the end of "Carla", as the in-episode credits only name "Carla".
What's confusing is that neither Carla or Sylvia are addressed by their name in the episode, and Julia Nickson looks like she could be either character! What gave it away for me was the size and build of Rose's brunette henchwoman (hehe, love that word "henchwoman"). The actress who plays the brunette henchwoman is shorter and stockier than Ms. Julia Nickson. The body shape of the actress who plays the street merchant is much more in line with Julia Nickson.

I've corrected the credits on the various pages (Video, Classic Scenes, etc.)
Thanks for pointing this out Sam
