Yes, that's probably the best guess I can put my mind to at present, that they might too be thinking their way around some semblance of interpretation in the broadest senses of the term. Could be vaguely idiomatic, too. (It cannot possibly be Sandor, though he's, of late, taken a turn for the worse, what else is left to do on GoT, and she'd never bother making a friend of his like, quite the opposite.)
Something else I just remembered, in the preview for the episode ahead, we do get to see Brienne rowing away from Riverrun castle, and she does not strike me as particularly happy to do so. Might be she's putting the carnage that is set to come about behind her for the time being, potentially worrying her head about casualties, too. If that's the case, my interpretation is that she's sitting out episode nine, and resuming action (or lack thereof, what was about bursting forth anyway) in the finale.
Which, to my notions, probably indicates that all ends are tied down to another cliffhanger (surprise, surprise), thus putting to bed the notion that GoT will be advancing book plots into new territory, hell, no, or not near enough.
Also all spoilers making Jaime's whereabouts as of episode eight a bit of a mystery to decipher, I'm thinking he and Brienne might reunite again next season on. I sincerely doubt they'd even consider bringing LS into the game (hee) after passing up every opportunity they had to do so, but it's entirely possible that was their plan all along. In the final analysis, Jaime might just go back to KL once more, in which case, I'll wager Brienne is left wandering the Riverlands under her own steam, whereupon she gets scooped up and faced with a conundrum as a result, or something kicks off and there's another reunion with Jaime. Bit of a headscratcher, really...
