The two are usually portrayed to be in a romantic relationship, though people sometimes go for a platonic approach. Hijack originates to a time before RotBTD when Rise of the Guardians and How to Train Your Dragon was a crossover on its own named How to Train Your Guardian.
Since Jack Frost (Jokul Frosti) comes from Nordic myths and Hiccup is a Viking, fans believe it could have been possible that Hiccup believed in Jack, and therefore been able to see him. Also, it is said that on Hiccup's native island of Berk it "snows nine months of the year and hails the other three". Though this could be a bit of an exaggeration, it is a fact that the island has some cold weather patterns, which could be a result of frequent visits from Jack.
