30 Days of Blake's 7 - day 13

Day 13: Favourite guest character

I'll pick three: Bellfriar and Gambrill from Killer for being interesting, fully realised characters whose reactions to and acceptance of Blake showed that there are many good people in the Federation, and Jarriere from Gambit for sheer charm, eccentricity, and his complete ease with Servalan.

All the questions are on Tumblr.
