Martel watches them, and she understands Zack completely. It may be a trap, but it may not be. And she won't force Zack to kill him. To know that death can separate them...he might have already killed him once. She won't give up, not if that's the ending that's already happened. This place is something of a second chance, and she refuses to see anything but. Not if there is a chance, not if this man that Zack so obviously cares for is still in there.

So she puts her all into this one spell, hoping that it helps, hoping she might be able to do something impossible. But then again, she's fought against impossible odds before. And truly, is anything impossible in this castle? "Revitalize!"

The spell circle appears again, casting a green light on everything. If Zack's injured from being caught by the tail, it's probably healing him too, as well as hopefully healing the other man.
