"It's safe to say that you might see more of [the White Walkers] this season," Harington told Kristin Dos Santos of E! Online. "We might learn a bit more about that. But when and where, I don't know," the actor added.

In the first four episodes of "Game of Thrones" Season 5, Jon Snow has killed Mance Rayder (Ciarán Hinds) in an act of compassion, chopped off Janos Slynt's (Dominic Carter) head to make a statement as an elected Lord Commander of the Night's Watch, and dismissed Melisandre's (Carice van Houten) seduction because he still loves the late Ygritte (Rose Leslie).

Stannis Baratheon (Stephen Dillane) wants Jon Snow to side with him in claiming the North. Snow maintains the Night's Watch let alone the ruler of them all does not participate in the war of the seven kingdoms. Melisandre argues there is only one war: life against death.

It remains to be seen how Jon Snow would react once he learns that her sister Sansa Stark (Sophie Turner) is about to marry Ramsay Bolton, formerly Ramsay Snow (Iwan Rheon). Petyr Baelish aka Littlefinger has arranged for the wedding, convincing Sansa to reclaim Winterfell. 

"Game of Thrones" Season 5 airs a new episode next Sunday on HBO.
