[X] Plan Fat Chance
-[X] "So it would strengthen the rule of Fey law upon the Reach, to the detriment of the power of mortal lords." // This is pretty much exactly what she has just said, but it bears spelling out for the Reachers to catch on. If Fey pacts become stronger and the only appellation court is the Fey king, then the Fey are now officially establishing a state within a state that bypasses mortal ruler-ship as inconsequential. Coupled with the admission that the Fey will have an easier time plotting, she might as well ask for Highgarden to be handed over.
-[X] "You may hide it behind pleasant words and claims of mutual benefit, but this is what your desires will bring in the end. A Fey court raised beyond the power of the lords of the Reach or any other mortal that they are sworn to. I take it that arrangements have been made that territory will be ceded to this new kingdom you seek to make? Maybe a pact or two forged to that effect in anticipation of binding the fool who made it tight as vice with your newfound power?" // Keep a cordial tone, but this is to pull Paxter and the other Reachers on our side, potentially even leading them away from the Tyrells, depending on what dealings have been made there. This worsens her bargaining position considerably and ensures that any violence she starts will result in Paxter siding with us over "the treacherous Fey".
-[X] "As I stated before, an independent realm in the Reach is not within my interest, especially so if wields to power to bind any and all around it to it's will with bargains struck by clever tricksters. You have been giving me plenty of reason why you desire the crown, but none why I should indulge you. You speak about bargains made, but you have not offered any such. So then, in plain and simple words so that this poor mortal can understand, if I let you have this crown, what shall I get in turn? Would your lord and his court be willing to swear itself to a mortal lord of the skill and character needed to ensure that your assurances about the benefits come to pass?" // The correct answer to the last question is yes, otherwise she just proved everything else we've just said and we gain Paxter as a consolidation price.
-[X] If she now proposes to swear to Mace Tyrell, just snort and calmly explain to her that you are not reassured. Either Mace is an idiot for missing the implications of this bargain or he is an idiot for thinking a independent Fey realm carved from the lands of his bannermen is a good idea.
