Another thing I did was think about the exact nature of the co-lords of the Darkblood coven, mainly, that while Dion lets Ruby handle most of the work, he still handles a few things. (In this case? Ruby has a no-killing rule, and Dion's trying to live life as a human, and MOST humans don't go around killing people so he doesn't exactly kill, either. Their coven has a rule against unnecessary violence as well, but them being vampires, they're fully aware that, sometimes, stuff happens...and Dion's the cleanup guy.)
Mostly an unproductive day aside from that.
