There is a continuity error here in that the Kings of the Highway were unknown to Reddington, yet they have a number on his Blacklist. It's clear they were not added to the bottom of the list (via a higher number), as their number of 108 is lower than several list numbers in Seasons 1 and 2. Additionally, since there were multiple criminals, each should have had their own list number as was the case in The Pavlovich Brothers (Nos. 119-122) (2014) where each brother had a number.
