Game Of Thrones Season 7 Implications: What "The Queen's Justice" Really Means
6. Sansa The Great Leader
As soon as Jon left Sansa in charge, you could practically see Littlefinger's arousal grow in his breeches. This would surely mean that he'd be able to get his teeth into her more and make her go after the Iron Throne herself, instead of all of this silliness about white walkers.
In reality, Sansa went about being the temporary Queen Of The North by being delightfully sensible, making plans to stockpile grain to ensure the North remains fed when the invasion comes and they all rally to Winterfell, and admonishing her blacksmiths for not covering their armour with leather to keep their soldiers a little warmer.
This is not the chaotic, bumbling leader we were led to believe was coming (but on reflection, she's not an idiot, so why would she go that way?). But that doesn't mean Littlefinger didn't try to turn her attention elsewhere: and you know what, for once, he made a lot of sense.
The North HAS to make allowances for their own victory over the Night King. If they don't, Cersei will steamroll them (just as Dany ignoring the white walkers in favour of Cersei will result in an inversion of that eventuality). So Littlefinger warning her to "fight every battle" at the same time in her mind is absolutely spot on.
He also commandeered the episode's important exploration of time as a circle. There are warnings all over this season that history will repeat itself (and that everyone is doomed when it does), and his allusion to everything happening simultaneously very nicely sits alongside Bran's reappearance and Jon and Dany clashing over Dany's insistence on past alliances repeating themselves blindly.
He's still an absolute sh*tbag, though.
