As we already know, SHERIFF SWORN (Aaron’s character) is not in S2 of HEMLOCK GROVE. Look at what I just found online from the TV Addict interview with Executive Producer Chic Eglee.
We were joking in a couple of threads on the facebook fanpage (HERE and HERE) that they’ll probably explain Sheriff Sworn’s absence in S2 by saying he blew himself up in his basement. From the sounds of that interview, looks like we were right.
