My BKA vote this month goes to Tabi Gweneth, for reasons that maybe not everyone else will agree with, but whatever. I loved this kill not because of who she was killing (that really didn't play much of a factor in my decision) but of the way the scene was handled, by all three involved. It was an emotion-filled scene, and definitely my vote for BKA this month.
For BDA, what do you get if you mix a humorous death concept with good writing and a huge dollop of originality? You get my vote this month, Richard Han/Geno. Not much can be said that hasn't already, but the sheer originality of this death, as well as the circumstances and the way it was handled (I loved him falling into a separate thread, thought it was a great touch.) Make this this month's winner for me.
