"Uriah got NSU from a woman he slept with"

In the Bible (as in this story), Uriah was the husband of Bathsheba. This would suggest that the narrator is concealing their real names from the reader, and therefore has possibly changed other names too.

NSU stands for 'non-specific urethritis', a sexually transmitted infection that is often caused by, or leads to, chlamydia. Since the reader has already been told that Bathsheba only gave the narrator 'emotional clap', this revelation again suggests his/her unreliability as a storyteller.
