Wrote a fight scene from the middle of the book yesterday.  Then I had the good luck to run into some fellow writers who very kindly walked me through the physical and emotional interactions that might take place in a quick, unplanned alpha-dog guy fight. This helped me get a better grip on the blocking/choreography involved. 
Another FW showed me the Casey Heynes bully video (slightly disturbing, and yet shockingly satisfying), which I had not seen. 
All in all, an excellent writing day.
