I'm trying to sort GOT characters into their respective hogwarts houses for myself and i came upon your list. I can't figure out where I want Lysa Tully/Arryn, can you give me your argument on why you think she's a slytherin?
Sure! I almost forgot I made this list! It’s been over a year.
I placed Lysa in Slytherin because of three things:
Her secret involvement with Jon Arryn’s death.
Her decision to never leave the Vale (and never letting anyone near her son) for personal safety.
How she used her marriage pursuers knowing full well she was dedicated to Littlefinger. She had many people under her thumb and ready to fight for her.
She kinda reminded me of a mix of Bellatrix (batshit crazy and in love with the worst person to fall in love with) and Narcissa Malfoy (very loyal to her son & fuck everyone else.)
She is very reckless at times, but usually only when it comes to Littlefinger’s affections. She isn’t loyal to any other member of her family (for reasons). And purposefully kept her very sheltered son from learning anything about the real world.
