CJL78: Well, Girona was a good province strategically since it isolated Rousillon from the rest of Aragon (which was severely weakened), it bordered Foix which was an independent nation under French Sphere which means, with the right turn of events, an annexation/vassalisation of Foix and provinces from France to connect the land parts. It helps to spread along the Mediterranean Sea if I can spread from two sides. It would also result in future conquest casus bellis in Iberia and South-western France.
One thing I didn't expect though was the rebels who seized Pirineo and Rousillon and formed Catalunya... Which by the way is guaranteed by England, Portugal, France, Castille, Aragon and Burgundy.
The world hates me.
