YMMV / Cursed (The Last Mockingbird9)

• Hilarious in Hindsight: On Game of Thrones, Littlefinger dies the same way as he does here, because the word of the girl he sent to Ramsay Bolton, begging for his life from Sansa Stark, and getting his throat cut. However in this story, Sansa does it personally rather than leave the duty to someone else.
• Tear Jerker: It's hard not to pity Littlefinger. He's been fighting the same battle his entire life for the hand of the woman he loved, and it drove him to do horrible things. And Sansa is horrified by the rough cut she makes in his throat. She hadn't intended on making him suffer.
