Yeah, I agree that it's a shame we can't have more major characters. Still, I think that even supporting characters can be good and should not be ignored. I've never seen 'Salmonberries' myself, I'll have to keep an eye open.
One of my favourites, whom I mentioned in my first post, is Jen and Amy from the Tru Calling episode 'Star-crossed'. Rachael Bella (Jen) I just adore. She's a really good actress and is really beautiful. Melissa Lee (Amy) is also good, although I haven't seen her in anything else.
Both of them do a great job in this episode. Their scenes together are very sweet and romantic, especially the scene where Amy gives Jen the necklace.
Another good thing is that the episode reverses cliche in a sense, since the truth about Jen and Amy's relationship is what prevents senseless deaths rather than causing them.
