Yunalesca: “Yevon’s teachings and the Final Summoning give the people of Spira hope. Without hope, they would drown in their sorrow. Now, choose. Who will be your fayth? Who will be the one to renew Spira’s hope?”
Yuna: “No one. I would have gladly died. I live for the people of Spira, and would have gladly died for them. But no more! The Final Summoning…is a false tradition that should be thrown away.”
Yunalesca: “No. It’s our only hope. Your father sacrificed himself to give that hope to the people. So they would forget sorrow.”
Yuna: “Wrong. My father…My father wanted…to make Spira’s sorrow go away. Not just cover it up with lies!”
Yunalesca: “Sorrow cannot be abolished. It is meaningless to try.”
Yuna: “My father…I loved him. So I…I will live with my sorrow, I will live my own life! I will defeat sorrow, in his place. I will stand my ground and be strong. I don’t know when it will be but someday, I will conquer it. And I will do it without…false hope.”
Yes! The Yunalesca speech is soo good. People generally seem to love that moment because of Auron's speech, but I think Yuna's part is even better.
And I've already answered the Yuna question when you asked about my favorite female character period.
EDIT: The answer was, of course, Yunie.
