Just started reading Dark Imperium over the holiday and there is a very interesting exchange between Guilliman and an Adeptus Custode. They are heading toward a station they want to attack and a human says that it is going to take X time to reach the destination. The Adeptus Custode responds that they are wrong and it will take X time to reach the destination to Guilliman. Guilliman then says that the Adeptus Custode has been away from humans too long and suggests that maybe the Adeptus Custode would like to take the other humans place. The Adeptus Custode just remains silent but it seemed almost as if Guilliman did not like the Adeptus Custodes or maybe was disappointed in them for turtling up and not helping the Imperium.
I am really curious. I'm I reading into this too much? Is Guilliman's feelings toward the Adeptus Custodes revealed at a later date and explained? Surely Guilliman knew that the human's calculations were wrong but he seems upset that the Adeptus Custode corrected the human. It just feels a little strange. Maybe Guilliman would have dealt with it another way other than just blatantly telling the human they were wrong and correcting them? It makes sense that the Adeptus Custode would do that. I mean, they are just under Primarchs in perfection and they are ancient and hyper trained in everything.
Anyway, anyone have any insight into this?
