Heard some spoilers from episode 8 script/leak. Not very big spoiler but... the "mystics" (the squad of Bridie Sisson) are all women. LOL. Also, the finale is basically them saying (about the Stranger) "He is not Sauron. He is the other. Istar." Also, it would appear the stars he is looking for would be in Rhun or something, and I guess all the Harfoots will follow him to Rhun... but all of that for next season...
You could see that coming, as there were two more of them in the background in the trailer. (I'm going to call that character Mystic Meg from now on). And they haven't been exactly subtle about the Stranger being a Wizard. As for the stars, that immediately made me think of the line "...even into the far countries of Rhun and Harad where the stars are strange."
Like I said the other day, also predictable that the hobbits would end up going on a mission. Quest. Thing with Weirdy Beardy. And if that's episode 8 we'll then have to wait until at least 2024 to find out what happens next. (So the Next Big Thing will likely be War of the Rohirrim, which is due out in about 18 months).
