I got it with blood and sweat, the only thing I used was the fleet, it is not in your claims, it was not yours so No I am not giving it back. If I were to do anything I would give it to the Rebels. It is my fair and righteous Property.
If it is blood and sweat you require, we have that aplenty. Or, perhaps, if you want to work out another deal? It sits unwell with our people for the head of a heretic religion to own land so close to our homeland, I'm sure you understand. So perhaps we could offer something else in return, without full on war.
There is no reason for you to need it. I will give one and only one option, I give it to the rebels. But, I do not see why you want it? Is it worth a war?
Give it to the rebels so. It's not that I need it, it's that I want it. Its purpose for you is fulfilled; the papal state is secure. It's too crowded up here anyway.
Aragon wishes to trade with the Merchant Republic of Norway. (Though we don't have a proper trade route set up just yet, the Crown assures you that we are working out Port, ah, arrangements with the French... in a manner of speaking. OOC: Maximus is away, so we'll just roll with whatever.)
The Merchants accept.
Splendid!
