A whole second backstory episode and it looks like we are getting a third episode next week fully devoted to Helck's backstory. It feels like a lot all at once. The backstory is appreciated as there has been very little of it up until now, but now it is the only thing we are getting at the expense of forward progress in the current time. I wonder what this is like in the source material. Is there just a whole volume of manga devoted to Helck's backstory?
