In just a blink of an eye after Gil had opened the cage and Walker had given an appreciative smile, the earth elemental mana has surged. The release of the earth elemental spirit had been like a dam being broken. All the natural mana that had been pulled toward the spirit was finally under its' control and waiting to be used.
"Free!!! I can touch the ground!" The spirit was overjoyed to be out of its confinement and free to touch the earth it was made of yet again. And elemental spirit being separated from the element it was made from would be the same as someone not being able to feel their arms and legs.
"Are you sure you want to help? I won't force you." Walker did not want to force the earth elemental spirit to do anything. It had already been held in a cage after being found and that was already unfair. Asking more was cruel in its own way.
