On an unrelated note, I presume we won't see Coldhands until series 4.
I´ve got a feeling that his appearence would be a pretty good cliffhanger for the next season, so hopefully he´ll turn up next week.
Btw, am I the only one who thought that the "conquest" of Mereen was pretty lame? I mean, three guys just walk into some badly guarded gate, kill a big group of well-equipped soldiers and then "convince" the rest to join their cause?
I´m also quite sad that we´ll never see Strong Belwas "dealing" with Mereens champion... :/
