Well, to be honest guys, I had NO IDEA the druid would attack. What I had in mind, is to say in no uncertain terms to the kobolds that I would slay the dragon, and then, as they refuse, draw my sword and walk towards the dragon, not initiating an attack on the kobolds, but responding to any interference they would put (which is what I assumed they would do).
Unfortunately, the druid didn't wait for that outcome to happen...
