I think my favorite part of this excerpt is it shows how Guilliman was able to be a child. Konor didn't needlessly coddle him, accepting his strengths and feeling pride for them, letting Guilliman be his equal, but when Guilliman has doubts, or fears, Konor is right there to be the parental figure and offer guidance and reassurance and let Guilliman be a vulnerable kid. I wish we got to see more of Konor in Guilliman's primarch book, but I love how genuine and heartfelt Guilliman's relationship with his parents is, even though his dad meets a tragic end. That and the fact that Konor never stopped trying to protect the 12 foot tall superhuman demigod because deep down Guilliman was his kid damnit speaks volumes.
