If anyone is destined to kill Petyr, I want it to be Sansa. But not because she hates him, wants revenge etc., but as a part of her own game of thrones. That would show us that she has learnt Littlefinger’s lessons and is capable of continuing the game, partly His game.
But, of course, I’d prefer if they just rule together. 😀
OK – my favorite characters on Game of Thrones are the strong women – Dernarys (sp?), Arya, even Cat (before, well, we all know what happened, right?), Brianne. Sansa is a bit of a victim. But maybe she will grow and learn. Maybe she will get in touch with her inner shield-maiden and stop thinking about “what’s a good catch” and “who can I marry?” Heck – I think it would be awesome if she realised how gentle Tyrion really is – and fell in love with him.
