So there are two things going on here. Snuff has obviously drunk so much that he’s in a black out. When you’re in a black out you don’t know you are. The people around you don’t know you are because you act normal (though tipsy). But your brain can’t make the memories of what you’re doing for you to remember (the next day). That’s why so many people get into so much trouble when they black out. “I did what? I said what?” I have Snuff in the last panel come to enough to know that he’s drunk and doesn’t know why he’s in hell. I like the idea that one can just wander into hell. The other thing going on in this strip is that Snuff’s mom is in hell. Did she die? Was she that bad? I’ll leave that for future strips.
