Well, if we go by traditional table-top handling, we won't know how the kobolds will react until it's their turn. Brannor should act however he feels if he has the chance to go; maybe he waits to see what the kobolds do, maybe he does what he wants to do. Unless talking here counts as a free action, there isn't really a way for Brannor to know what their answer is until they do something, which by at that point who [i]knows[/i] what they do.
