Her advice was common sense, it wasn't so great tidbit of wisdom.LifeCharacter said:Well except Sansa offers Jon probably the best advice anyone had given him and he not only fails to follow it but fucks everything up by ignoring what she said. She told him Rickon was a lost cause. She told him that Ramsay wasn't going to fall for his trap and that he'd most likely fall for his and that if he let that happen he'd lose. Then Jon immediately abandons the battleplan to try and save the lost cause and then decides to charge Ramsay's army by himself, forcing his own army to charge in to save him.
Jon could have delayed the encounter if he knew that a massive army was coming to support him... he pretty much knew if he was a goner as well, which usually leads to one acting irrationally.LifeCharacter said:Jon would have been baited into the charge regardless of if he knew reinforcements were coming, because it wasn't a sound military decision but a completely emotional response to his grief and anger. And since the battle isn't exactly a long one, there would be no real way to avoid Ramsay's bait. Jon would need to have an unreasonably specific idea of when the reinforcements would come and know exactly what Ramsay would do to avoid succumbing to the exact same thing; the second they form up, Ramsay throws his bait and Jon abandons his plan.
I don't think he would have charged, or even organized his forces to meet Ramsay's so soon, if he knew that the battle was won if he waited a bit longer.
