Well, they pulled the trigger with William
I was glad that they didn't draw it out, and very glad he didn't die in the same episode where they revealed where Jack died because that would have been too much. But I will miss William, and the incredibly talented Ron Cephas Jones (who I'm sure we'll see again, but likely not as regularly and not in this incarnation).
Alas, given the promo for next week, and there only being two episodes in the season, it seems Jack almost certainly dies while Rebecca is on tour.
