Warning: Spoilers ahead

Reddit user ALL_STAR_87 has come up with a theory about a possible marriage that could happen in the seventh season of "Game of Thrones."

"Could Sansa Stark and Dickon Tarly be the pairing Westeros has been waiting for?" the Redditor suggests.

"Randyll Tarly is clearly the driving force behind the recent Lannister alliance, while young Dickon shows more concern about turning his back on old ties.

"If Randyll croaks and Dickon survives there's a chance he could abandon his father's pact with the Lannisters, paving the way to reconnect with his brother Sam – who happens to have the Tarly's Valyrian steel sword and coincidentally is best mates with a Stark.

"With the Starks/Targaryens looking likely to take on the walkers, Sam bringing House Tarly (and most likely the rest of The Reach) onboard would be a big strategic win. Not to mention that House Tarly supported the Targaryens back in the day.

"By joining the fight in the north, Sansa and Dickon would no-doubt cross paths setting-up a potentially perfect partnership bringing together north and south."

If Dickon gets captured by Daenerys after surviving the train loot attack, marrying him off to an ally could help bind the Targaryen cause.

Dickon's survival may mean that he's still got some part to play at least in upcoming episodes.
