Dose anyone else think that Bracken can take a lesson from twilight?

both yes and no.
he does need to get that age doesn't matter because look no matter how long you wait there will always be that age gap between them. get over it you can't change it. he doesn't however need to make her an eternal (though it would help) because time is precious and there is only so much time before it's gone.

Bracken has a great shot as long as Kendra somehow becomes immortal, if she does't he will be devastated. Kendra could become an eternal.

Kendra can become an eternal or while making keys can ask for a imortal magical artifact!
