I have rescued Demise, Ganondorf, Link (who's unconscious) and Pyramid Head successfully. I am healing Ganondorf's wounds from being tortured and I somehow talked some sense into Demise.

Demise. There is a way to bring Zelda back, as Red Shadow remembered, but it might not work, but it's worth a try. It'll take a few days, but it'll be worth it. You will get your sister back...I promise.

I am okay. Who knew light shields were so heavy!
