[This article contains SPOILERS for The Walking Dead comic book series.]

While everyone waits impatiently to find out who Negan killed in the season 6 finale of The Walking Dead, there are other mysteries in the comics that fans have waited even longer to find the answers to. Perhaps one of the oldest of these is the fate of Jeff Grimes, Rick’s long-lost kid brother who was first mentioned way back in The Walking Dead #3.

This particular mystery has finally been solved, however. A special digital issue of The Walking Dead titled The Walking Dead: The Alien reveals where Jeff is and what he’s doing even as the world is overrun by the undead.

The Walking Dead one-shot comic is available at PanelSyndicate.com and was written by Brian K. Vaughan with art by Panel Syndicate founder Marcos Martín. The comic was part of a deal with Image Comics to allow Vaughan and Martín’s digital series The Private Eye in a hardcover collection. The Alien is a DRM-free digital download with a pay-what-you-want price point, allowing fans to download it in PDF, CBR or CBZ format for as little or as much as they wish. And for those who are wondering, yes it is a canon story within the Walking Dead universe.

The story opens with Jeff Grimes in Barcelona, Spain, sleeping on a scaffold and waking to the sound of a young boy screaming in terror. He tries unsuccessfully to rescue the boy from a group of walkers, soon finding himself in need of a rescue of his own. When he meets his literal knight in shining armor, he finds out that there’s still a chance that he can escape the city and make it back home to America to find his brother.

The Alien‘s story is self-contained, but it gives readers a view of the world far removed from that of the main cast. It’s touching, depressing and well-written, just as a story from the world of The Walking Dead should be. Given Kirkman’s comment about how it’s canon and “matters,” it’s possible that we may even have gotten an introduction to an eventual addition to the cast of the main The Walking Dead comic.

While it’s unlikely that the events of The Alien will ever be touched upon on AMC’s The Walking Dead, it should still be a fun read for fans of the comic. Remember that comics published at Panel Syndicate generate revenue directly for the creators, and that the works are created and put up for distribution before any payment is received for them.
