But ES is connected to ROE. Also, Nighbound has been confirmed to be a spin-off to Bloodbound because the writers said so. Also, just look at this (https://en.wikipedia.org/wiki/Spin-off_(media))


 * In short, NB is a spin-off from  BB (like Class Act is to HSS and TRR is to TRH ) because it comes from an already existing work (BB) that focus on more details and different aspects from the original work (e.g. particular topics, characters or events) ---> NB.


 * The same wikipedia link says a spin-off can also be applied to works that exists in the same chronological frame of time as its predecessor work. It's just more commonly referred to as a Sidequel. With this in mind, ES, is a spinoff, or sidequel of ROE. TRR is a spinoff/sidequel of ROE and TC&TF.
