It's giving that empty feeling with the ending only with Yohan, because it started with him and it'll end with him. If there was Jay with him at the end, i think it'll be giving that cathartic feeling, but that shouldn't be the case. He found peace, but that hollowness created from the death of your loved ones will always be there
