^^I was just thinking that watching last episode, koko!
Arya is so brave and clever. Sansa saw with her own eyes what a little bastard Jeoffrey is, and still she is still smitten with him. Bran also is clever and brave. Sansa is quite feeble and doesn´t seem to have deep convictions or beliefs, she just kind of goes with whatever they propose to her. Yes she definitely needs to do something to redeem herself.
Loved how Robb is so in command and being a man now that his father is in danger.
Lysa Tully (I´m not sure here, she´s Catelyn´s sister, right??) well, she definitely gives me the creeps, with that strange grown up kid by her side, always wanting to "feed" from his mum. Sooooooooooooooo creepy
