And at the end of the season, and episode 16: Bernie Wrightson. According to The Independent,
Bernie Wrightson. Wrightson was an American artist best known for co-creating popular horror character the Swamp Thing as well as an array of other popular horror comics.

So, there you go. Now you know.
As for the season: it ended as each season's been ending a long time now, with potential for a continuation. It's like they're dragging out the plot as well as they can, to lure in new viewers, and keep old ones like me coming back, but at this point there's really nothing new to it. No twists. No new characters. No revelations. People go back and forth and get themselves a trouble, and it all boils down to the same thing once more. Redemption. Revenge. Slaughter. Fighting for those you care about, and though it maintains the tension well, and ends with a killer show, it's getting tiresome. There's no conclusion. No satisfaction. No end in sight.
That's why I watch this series in marathons, instead of just one episode at the time. I'm not the kind of person to spend my time looking forward to the next episode, when I know the next episode is just an excuse for another, and another, and... I don't want to know how it all ends, though! Come next year I'll wait till the next season's out and catch up then, and hope it's over. Like a movie.
I don't expect it will be, but hope's what keeps us alive right? Without it we'd be just a huge, collective, walking dead. And it'll just spread like a series.
But at least some interesting names popped up this season! RIP James, and Bernie, and all the rest who didn't make it past this season.
