When Adramellech attacked the heroes with that tremendous blast of energy, Elizabeth realized that Relm had rushed to cover them all with his power so they would all be unharmed. This wasn't something she was expecting. It never happened in the dream she saw of these events.
Elizabeth: {Is he… our ally? I thought all four of them were trying to kill me and the others… It seems as though I was mistaken… he is helping us! If that is the case, then there is still hope!}
Relm had collapsed on the floor, and Legend was holding him up. He was barely conscious, and it seemed like he was dying.
Legend: Rachel! Can't you do something to help him?! – Legend said urgently.
Rachel then used the magic spell called Cure to re-animate him. As she saw it didn't do anything the first time, she tried one more time. And again... and again. There was no effect. For some reason, she couldn't heal him.
