Spoiler Alert for ACOK.
You know I am the chief anti-Ygritte hater, but after Jon killed Qhorin in the last episode of season two and Ygritte threw back her hood and said, "Come on, Jon Snow"... well, I softened towards her a little bit. In the books she's always cold, mocking, pig headed, or randy. But in that instance, she was soft... and I liked it.
