Three years ago, Jason Aaron wrote a scene in Original Sin in which Nick Fury whispered something into Thor’s ear that made the Odinson unworthy, and therefore incapable of lifting his mighty hammer, Mjolnir.

It has been a long wait, but fans are finally going to learn the words Fury spoke that undid the God of Thunder. Marvel Comics has confirmed to ComicBook.com that Nick Fury’s whispered words will be revealed in the fifth and final issue of Jason Aaron and Olivier Coipel’s Unworthy Thor limited series.

“I always said we'd eventually find out just exactly what Nick Fury whispered to Thor Odinson that made him unworthy,” Aaron says. “The words have been scribbled in my trusty Thor notebook for years now. Words that speak to the overall story I've been telling with this character going back to Thor: God of Thunder #1. The next phase of that story begins now.” After the Odinson was made unworthy, a mysterious female Thor began operating in the Marvel Universe. While Odinson has yet to discern the Goddess of Thunder's identity, she was revealed to readers as Jane Foster, Thor's former love who is struggling with cancer in her human form.

“I remember when Jason told me what it was that Nick Fury whispered, it just felt so satisfying – like, it’s definitely a big curveball, but it feels so organic to Jason’s overall larger Thor story – it feels earned,” adds editor Wil Moss. “If you’re looking for some insight into who Thor Odinson is as a character and if you’re looking for a sense of where Jason is going to take things from here (both with Odinson and with Jane – and with all Ten Realms!), then brace yourself, ‘cause this secret hits harder than Mjolnir.” More Marvel Comics: Ranking The Thors Of The Marvel Universe / Jason Aaron Leaving Doctor Strange / Everything Coming From Marvel In May 2017

The revelation will come in an issue that already promises a showdown between Odinson and Thanos, as the former God of Thunder attempts to lift the Mjolnir of the Ultimate Marvel universe.
