I don't. Intrigue me.

Anyway, ditto this:

This is why people tend to disregard connections between Higurashi and Umineko as humourus fanservice. If you're familiar with most of Higurashi, you can catch plenty of silly little connections between the two series, from the Higurashi mystery novel to how Furfur and Zepar's outfits resemble the Angel Mort uniforms from Higurashi. Because there's plenty of pointless connections like these, people have are more reluctant to theorize about serious connections, like Bernkastel = Frederica and such.
