So they made Hightower a young man despite pycelle later on talking about him as if he was old
Also Idk why but I lmao hard when u said the dude is dead
Well despite the "Hightower" is supposed to be the official version, the actor who played it tweeted that the character was an amalgamation of both When and Hightower.
And he's dead, isn't he .-. that memory is important because of what has exactly transpired within the Tower of Joy, so that some odd Dornishmen died in the scuffle before it I doubt is important. Unless they decided to recycle a small plotline from the books. An important Northern lady hated the Starks, or in particular Eddard Stark, and was also one of the first to support the Boltons. She was in love with Eddard's elder brother Brandon and he loved her (or at least that's what she believed) and they were planning to marry (or so, again, she believed). Brandon did stole her first time though, however soon after that he was betrothed to Catlyn Tully. That of course went sideways when Brandon was executed by the Mad King and Eddard took his place, married Cat and started the rebellion. In the mean time that lady (I forget her name) married another Northern lord and that lord was one of Eddard's companions at the Tower of Joy. Of course he died, but Eddard only brought back the body of his sister, all the others were buried at the Tower. This all made the lady strongly resent the Starks and Eddard in particular because she felt like they had stolen her husband twice.
Now in the books this wasn't important as far as we know and just was meant as some background information (which happens all the time), though maybe they recycled it into a different plot involving Dornishmen. Personally though I sincerely doubt that.
