That's so true!!!!!! The last season made the whole series feel pointless
Not really.
Why did Arya even bother learning how to put on other people's faces if she didn't use it?
I'm sure she'll use her lesson's the farther west she travels
Why did Bran bother becoming the 3 Eyed Raven when it didn't seem to help anything?
Not yet, but it will, patience
What's the point of the Wall or the Watch, if there aren't any more White Walkers and they're all good with the Wildlings now?
did you not notice that the Wildlings and Jon both left the wall and the watch behind.
When Sansa declared that she was going to be her own queen and stay separate, why didn't the others do the same thing?
could be a plot twist to a new series or it's hard for some of those leaders to be independent of others, their safety comes in numbers.
Especially the Greyjoy woman? Wasn't secession the whole problem in the beginning of the series, anyway?
for her it was...but it may not be in the future for the Iron Islands
If Arya wanted to know what's west, why didn't she just ask Bran?
Bran see's the past, not always the future...that was the Red Witchs call.
