"Since you had no intention of making it public, why did you come to Chogoris to sneak around and steal things?!"
Jaghatai bellowed. He did not believe Guilliman's explanation.
His brother was skilled at politics. Who knew what schemes lay hidden beneath that resolute, honest-looking face?
Guilliman saw Jaghatai's suspicion and put on an anxious expression.
That anxiety contained three parts deliberation and seven parts sincerity, all perfectly conveyed through Guilliman's facial muscles.
"Brother Jaghatai, the reason I did something so foolish... was entirely because... because I had a guilty conscience..."
"You had a guilty conscience?"
"That's right, Brother Jaghatai." Guilliman rubbed his forehead and sighed, explaining why he had been so flustered.
"Among all our brothers, my Warp essence awakened the slowest. Do you know why?"
Jaghatai pricked up his ears. He seemed to have some inkling of what Guilliman was about to say. "Why?"
Guilliman's face went red, then pale, then red again.

Jaghatai fell silent. His most despairing moment had been when Guilliman discovered the secret books in Chogoris's library and made them public.
