Latest episode (S7, E5) spoilers below;
So the "teleport"/"fast travel" method was in full display tonight, eh? We had Jaime and Bronn travel from Highgarden to King's Landing, Davos and Tyrion travel from Dragonstone to King's Landing AND back, and Jon's group travel from Dragonstone to the Wall all at different times in the episode. I don't really mind it, but after not employing this method of travel during the first six seasons, it's strange to do it now. That's the price to pay for shortened seasons, I guess.
I also don't quite get this quest to capture a wight. I can't see any way of it working, and it doesn't even seem like a feasible option that they would consider. It also has a Cersei trap written all over it. I don't really like criticizing show's that I'm this into, but to me this part of the plot seems like poor writing that I'm not really buying into.
Granted, I'm loving the dynamic of this group: Jon, Tormund, Jorah, Davos, Clegane, Gendry, Dondarion, and Thoros of Myr? That will be entertaining north of the Wall!
