The uncharted territory of Game of Thrones Season 6 has stirred a great deal of interest among which characters might return, some confirmed, and others overwhelmingly suggested. Now, two more names have entered the fray, as evidence might put Natalie Tena (Osha) and Art Parkinson (Rickon Stark) in Season 6.

Take this one with a grain of salt for the moment, though it seems Game of Thrones’ Belfast production may yet again have given away returning characters, as Watchers on the Wall brought attention to an Instagram post seemingly confirming Tena and Parkinson’s presence In Ireland. Like his brother, Rickon is certainly looking a bit older these days:

Like Kit Harington, little beside the actors’ presence in Ireland can explicitly confirm their role in Game of Thrones Season 6, but there are any number of reasons to check in on Osha and Rickon, who last appeared at the end of Season 3. In the books at least, Davos Seaworth is tasked with retrieving Rickon from his rumored presence on the island of Skagos, though the series would likely need to modify Davos’ involvement anyway.

Elsewhere of Game of Thrones Season 6, screen legend Max von Sydow has been cast as the mysterious Three-Eyed Raven to a returning Bran, while Deadwood alum Ian McShane will also appear in a limited, mysterious role. Apart from a list of directors, debate continually rages as to whether Kit Harington’s Jon Snow will participate in Season 6, even as Harington can clearly be seen in Belfast, and story logistics seemingly confirm scenes set at The Wall next year.

We may yet have an additional two seasons beyond the sixth year to pad out George R.R. Martin’s vision, but what else can we infer of future Game of Thrones from Osha and Rickon’s return?
