Great update! Looks already like Catalina is finding happiness in Spain and a happy Catalina is a Catalina that I can get behind! Hopefully having her youngest daughter around will help Isabella transition peacefully into the afterworld and fill her final years with some (surely much needed) comfort.
Thank you for your praise, I am truly humbled... Yes I think Catalina will be happy in Spain, remarriage isn't out of the question but it won't happen for a while due to certain pressing matters that will come up with her patrimony. I think Isabella will indeed be comforted by her youngest daughter being with her in her final years, and perhaps she'll find a little peace knowing that her daughter is safe and back home.
