Cane knew that Iris was a sleepyhead, she could literally sleep anywhere whenever she felt like it, even on the moving horse. She still managed to sleep soundly.
Her pregnancy seemingly increased that ability. From what Aliana told him, Iris happened fall asleep during her dinner and she needed to wake her up to continue eating.
Right now, she fell asleep, while listening to Lou's report, as if he was giving her a bedtime story.
"I can't with the two of you!" Lou grumbled. He had exhausted his energy when he blew up the magical device and created a portal to come here, that was why, he barely had enough strength to lift his fingers, let alone walked out of the bedroom and avoided these shameless couple.
Yet, his eyes softened when he saw Iris's side profile. She indeed slept well.
