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.

His personality would shift from the carefree spirit we know to a brooding and vengeful being.
One possible plot could be that Jack Frost is corrupted by a dark force. He starts to spread winter not as a fun, playful season but as a harsh, unforgiving one. He might turn against the other Guardians, believing they are holding him back from his true power.
