Why wasn't there a kill last Night?

The narration almost indicates that it was done on purpose, but I can't see why the wolf would try such a risky move even if it was for a setup. I'd think that the final wolf would want to play it safe and eliminate the number of players as fast as possible, but maybe I'm wrong. Though with so many players having RL issues going on, the possibility that the wolf simply made a goof and forgot is quite plausible.
Oh goodness, I had to get up at 4am this morning for a flight and after a four hour nap I'm still dead tired.

I'll be around later this evening hopefully feeling a little more alive to post some thoughts. Even though I should probably be doing my homework at that time. Oh, how WW is a great way to procrastinate...
