Can someone explain the fourth panel? What's the significance of the big red X and why is the background a pair of idiot knife ears making out in that wooden hellscape? I know it's nauseating to look at their weird bald faces for too long but I'd appreciate the help. Probably some human nonsense.
(The choice between a "daemon in the sheets" or "cronD in your log folder" joke is left as an exercise for the reader.)
