circa the end of 3x09. general advice and then specifics on how he's changed would help me a lot, especially describing his brand of wit.

I'm told I'm doing well with him so far. but I tend to function almost entirely intuitively and am only taking in canon review and my understanding of him in a nebulous emotional way, and sometimes reading how others have put a character into words, into something solid and concrete, helps me a lot.

therefore, I'd be very grateful for any and all help :)
