This is the disembodied voice of a great spirit that Guest wasn't supposed to see. It whispers words to Guest. "The growing pains" is just what Guest calls them. When they went into the forest they saw a spirit of a massive buck. This is the voice of that buck. It doesn't want Guest to become an anthropomorphic deer, in fact it's actually sad that it's happening. Often apologizing while trying to guide them through the pain, trying to ease their mind. It knows that Guest will become a deer whether they want it to happen or not, the only thing this spirit can do is try it's best to soothe the pain. It is sad to see Guest change, but knows that the only thing it can do is accept this.

This is the voice that Guest hears that tries to cling to humanity. It's cruel and cold. Its words are meant to cut and betray you, it thinks it's helping. Like pulling a knife from the wound. Its a desperate attempt to make something stay the same as it was before. Thus is the aspect of humanity that clings to survival. It doesn't say cruel things to be cruel, it just is a thought in a changing mind. Like frustration in change.

This is the part of Guest birthed from their new changes. Encouraging you to lose yourself, to become wild and free. It can feel the heart beat. It senses the growing instincts and comforts them. Allowing Guest to slip deeper into acceptance. Probably the best way to live this new life.
