Vilja is a great companion! Funny, quirky and adds a level of interaction not found anywhere else. Her dialogue with Inago is actually getting funnier the longer they quest together. Now they are arguing over who should do the sweeping! My other favorite companion is Arissa. Totally different personality though. I do not see them as close friends, Arissa would think that Vilja was too naive and girlie in an annoying little sister sort of way. Vilja would be in awe of Arissa's fighting and thief skills but think that maybe she since she came from a rich family she was playing at being bad and so would tease her more than she teases Lydia. Any thought on adding dialogue with Arissa?
Arissa is no longer being supported by the author, Chesko and it is uncertain whether he will ever do any further work on her in the future. It would of course be necessary for both authors to cooperate if mutual dialogue was to be added.
