The pain comes, tied up with the extra life energy. Too much of it, too much for her body to take, but it flows eagerly into him, like water into dry ground. (Warm and sweet and it feels like Ibani in the Force, because it has become HERS.)

He can take the pain away, IF he takes the life energy into himself. (He's spent so much of his life energy over the years that he has 'room' for lack of a better term.)
