The episode opens on Worwick having a nightmare of a flashback from his childhood, we see young Worwick surrounded by his dead family crying, we later find out that 22 years ago, someone massacred Worwick's whole family. In the flashback the murderer looks like Nicolas and is hinted as such, but we will see about that, if it was him that killed Worwick's family that's a really interesting relationship for the two to have.
We also find out that Worwick is a gigolo and has been since he was 13, this was a strange job for Worwick to have, and makes Worwick a very confusing character for me to get my head around, it seems like he could quit doing that job but maybe he enjoys the job!
