Jack never asked Hiccup what made him accept Pitch's offer. Pitch Black never doubted that Jack's love for Hiccup would keep him on his side for eternity. [Major character death(s).]

There's always friendship and love, and people always leave. Sometimes they come back. [ HTTYD1&2 Rewritten with Jack Frost in the picture. ]

He'll never be able to take it back. Forgiveness exists, but so does Darkness. [ Set after the first HTTYD movie. Before the second one. I'm horrible at summaries, there might or might not be a happy ending. ]

Modern Hijack AU. [[Major trigger warnings.]] Following in the footsteps of their fathers' friendship. Life isn't easy, love is hard to find, especially when it's staring you right in the face. ( Happy ending, I suck at summaries. )

Modern Oneshot AU. Hiccup's crush confesses her love to him. Little do they know he has an invisible admirer. [Major Character Deaths]

Continuing after the end of HTTYD2 (Implying that Astrid and Hiccup were never romantically involved). Base: Jack Frost is a winter spirit only seen by dragons and, mysteriously, Hiccup. Summary: Hiccup wakes up with the realization that Jack will never grow old. (R&R are appreciated)
