What is dead may never die. If only that were true for Game Of Thrones fans who have witnessed more key character deaths than arguably any other show currently in circulation. Committing to the award-winning fantasy series is not for the faint of heart, when no beloved character is exempt from an often merciless grizzly end.

Occasionally, grieving fans do get a reprieve from the misery - the bonus of a fantasy series is that miracle resurrection (although seldom) is not impossible. Failing that, a decent magical vision can be an opportunity to revisit the fallen - even if it's just for a few minutes. This is what many fans will be hoping for, following a series of Instagram posts from Jason "Khal Drogo" Momoa.

Khal Drogo, the Dothraki ruler husband of Daenerys Targaryen (Emilia Clarke), met his grizzly end via an infected wound, some ill-advised black magic, and subsequent euthanasia in season 2. The character returned for a bitter-sweet post mortem cameo during Dany's vision in the season finale, but has not been featured since. Momoa has continued into film following his Game Of Thrones death, featuring in Batman v Superman: Dawn of Justice as Aquaman with a solo Aquaman movie due for release in 2018. So why was the actor posting Instagram pics from Ireland, where a significant portion of Game Of Thrones filming takes place? And more significantly, was his meeting with showrunners Dave Benioff and Dan Weiss more than just a catch up between old friends? Check out Momoa's image below (via Time):

In addition to this speculation fueling post, Momoa also shared images from his visit to Dublin's Guinness brewery - which may well have been the purpose of his trip to Ireland, although it is unlikely that Game Of Thrones theory loving fans will chalk his reunion with the showrunners up to coincidence.

Despite the intriguing nature of Momoa's posts, the timing is slightly off to really be certain of anything at this point. Season 7 is still in pre-production and no other cast members have been reported arriving in the country for filming as of yet. Recent tweets from co-star Maisie Williams (Arya Stark) suggest the actors have only just begun to receive their scripts at this stage, and filming traditionally begins in October (possibly even later this year, as the season air date has been pushed back to summer 2017 and winter has finally come to Westeros).

Due to plot developments within the show that allow for showing events outside of the timeline - such as Bran Stark's ability to have past and future visions, it is now more likely we will see dead characters returning for additional scenes to further the narrative. It is entirely possible that Momoa's post could signify a future reprisal of Drogo. It would also be amiss to forget that this is exactly what Kit Harington's presence in Ireland last year was about - despite insistence to the contrary. With Game Of Thrones, you can never say never.

Game of Thrones will return in 2017 on HBO.
