..so now we know ...I guess it was plausible, how they did it because he could have slipped from beneath Nicholas in a few seconds..and good to see more of Enid again, she's still a bit of a mystery...another great episode and a huge cliff-hanger ending as the tower collapses at the walls, just as Glenn arrives back, so we still don't know if any main character will be killed off just before the season break....
