Dany in the desert (and here) have strayed to s02e04, whereas they belong to episode 3 (I have smaller resolution pics from these scenes that show this).
Promo shoots of Finn Jones (and this) to episode 9, Blackwater.
A bloody Jon Snow at Craster's Keep to episode 3. Ser Amory Lorch (Fintan McKeown) goes there as well.
Jonas Slynt, commander of the city guard, has just tortured Gendry's former master Tobho Mott into revealing that he sold Gendry to the Night's watch, which happens in epidose 1. (See very similar image here, featuring Mott's bloody face)
