Predictably, Strong Belwas, Daario and whatever other characters were around Dany in the books have been merged into one Daario.
I feel a bit reassured that lack of Aegon and Jon Connington is not yet guaranteed but concerned by Varys travelling to Meereen too? Sadly I think that storyline will be cut.
Though probably casual viewers forgot Kevan and Lancel existed, good that they're there, King's Landing storyline needs 'em.
Probably most intrigued by Sansa and Baelish because they're ahead of the books. Cowboy's theory seems silly though, what's the benefit for Littlefinger for helping or crossing the Boltons?
And I guess Mance as singer in Winterfell is a no go then.
