I say we give her a little food if we can spare it under the warning that if she or any of her kin returns in hopes of finding handouts they will receive none. But if she wishes to come back for trade, diplomacy, joining the fort, or anything else that benefits both our groups we will let her, under cautious supervision to make sure that she isn't coming to steal anything. If any hostility is sensed or intentions of sabotage realized, she is to be thrown out and attacked on sight upon return. We should also push to find out just what she means by "family", sometimes that could mean one kid or an entire kobold den. It would be helpful to know if she plans on bringing her whole den over in an attempt to milk our hospitality. But if it is a whole Kobold den then they might be able to bring us items more valuable than just trinkets. They'd be stolen of course, but no one's going to come looking for them up here. The consensus seems to be that no one really minds her, except Chedna, so I guess she can stay for a few hours while we prepare her for her journey home. But we would have to do something to make some kind of statement to her that we mean business and aren't an easy target while still being open to potential friendly diplomacy. I'm not sure what that would be, maybe Chedna tackling her was enough? Diplomacy is always a delicate matter, especially when dealing between species that have different ethics. If possible I would like to try to find out as much as I can about her people's particular branch of Kobold ethics so we can better relate with the Kobolds of this area in the future.
Edit: I realize now that there is probably no way that I'm going to be able to discuss anything as complicated as diplomacy or ethics to a Kobold. But I would like to try, turtles have some incredible patience.
