The Klaus thing you're probably talking about was supposed to be a Halloween kind of thing, I'm not sure if he's still getting a route, but I'm sure if he is getting one it'll be less scary, albeit probably still a little spooky/eccentric given his demeanor. No other scene in the game is like that, so far.
*Only unsure about Klaus, b/c waaaaay back in some of the original builds it seemed like Travis may have had a route if enough people liked him, but alas he did not, thus he won't be getting a route, and I don't think Klaus is that popular. There's still certainly a chance though and I could very well be wrong.
