It will be fascinating to see how the characters evolve as Rebels progresses. Especially in light of what is revealed in the book, that the Jedi ban on romantic relationships is not part of the Jedi Code but an addition to their rules for life later.

I'm having trouble understanding what exactly that line means. Is the reviewer trying to say that the "no attachments" rule is something that wasn't originally part of the Jedi Code but became dogma years/centuries/millennia later?
