I'm playing a tiefling druid at the moment and before trying to save Arabella, I used Speak with Animals on myself. I was then able to talk to the snake Teela and explain the situation to her - she was much more understanding than Kagha and actually tells Kagha to stand down. That is so nice. I don't think, you have that option with anyone but a druid, since the option is labelled as the druidic answer.
