When you get into the goblin's mind, and reveal her vulnerability - after Martha's view of her, which is threatening, sexless... that rocks.

I'd say go with that. I'm concerned for the goblin girl. Worried about what will happen to her once her message is dispatched.
Wondering what her message is. It could set in motion any number of plots. A message, two characters, a nameless, powerful villian, and the threat of sexual exploitation... aw yeah. what're you talkin' about, no plot?
