He might isolate himself, which adds to the overall sense of melancholy in the story. The detailed descriptions of his inner turmoil can be quite moving.
One of the most prevalent themes is the power of belief. In the 'rotg' universe, belief is important, and this can be incorporated into the relationship between Jack Frost and the oc.

There could be situations where either Jack or the oc has to sacrifice something for the other or for a greater good, which adds depth to the story.
