One thing that's always bugged me and sorry if this has been answered elsewhere: wtf happened to Martok's bitch-slapped son from Way Of The Warrior? Unless I missed something, feels like he's never mentioned again, and fact that Worf was the one who dishonored him doesn't seem any impediment to him being accepted into M's house.
Knowing Klingon customs he was probably dishonored for being slapped around like a little bitch and committed ritual suicide.
Actually J.G. Hertzler remembered Drax being he used him in his Left Hand of Destiny novels.
