I saw Sandor’s last scene and sure, he didn’t die and he mentioned Sansa. We should count our blessings, right?
Except when Sandor expresses regret over not fucking Sansa bloody and killing her (why do people always take at face value the first part of what he says and completely ignore the second part in which supposedly Sandor expresses genuine regret over not killing Sansa? Because that’s harder to take at face value, isn’t it?) it is not because raping Sansa would have made him happy (that is literally what show!Sandor says). It is because had he done what he wanted to do to her/what he feared he could have done t her - that would have saved Sansa from Tyrion.
He made a queer sound, and it took her a moment to realize he was sobbing. “And the little bird, your pretty sister, I stood there in my white cloak and let them beat her. I took the bloody song, she never gave it. I meant to take her too. I should have. I should have fucked her bloody and ripped her heart out before leaving her for that dwarf.”
Yes, it’s fucked up and violent and ugly and terrible and probably a lot misguided since Tyrion might not be a good thing that happened to Sansa (it wasn’t) but it also wasn’t the horrible fate Sandor imagines it was. BUT IT WAS REGRET ABOUT NOT SAVING HER, SHAPED-UP TO THE MOULD OF SANDOR’S EXTREME SELF-LOATHING.
Sandor didn’t fucking die thinking of how raping Sansa would have made him so happy. However, he would maybe say that to get Arya to kill him,
So yes, he was goating Arya, desperately trying to give her a reason so that she’d kill him. It’s pretty obvious. But in the show, we’ve still lost all the nuances of the original text, in which Sandor, while saying horrible things he really doesn’t truly mean to get Arya to kill him - also manages to both confess his darkest demons and actually (kinda) atone for them, if you read carefully and pay close attention to the syntax.
But. I will give something to the show writers. The fact that it makes absolutely no sense whatsoever that show!Sandor would ever have wanted to rape Sansa, much less the night the Blackwater burned - as it is evident in 2x09 that nothing he says or does seems to point in that direction -
"You won’t hurt me."
"No, little bird. I won’t hurt you."
- then at least the show does a good job in overtly exposing that what Sandor is saying is a LIE and that he is saying horrible things just to get her to stab him through the heart. Sometimes, horribly continuity works in favor of halfway-decent characterization.
