After having a lengthy talk with Atropos, during which he learned many important things, Sam left the two sisters to continue their conversation.
"Let's go."
"..."
Upon receiving no reply, Sam turned around and gazed at the Valkyrie serving as his guard. Miku hadn't moved from her place, her head slightly lowered as she stared at the floor.
"Miku, if there is something you want to tell me then…" pausing for a moment, he breathed in and braced himself. "Then don't hold back. I know why you're angry but… I want to hear it from you."
After returning from the Nephilim world Sam found himself with quite a lot of work to do. He had to ensure that the Fallen Worlds wouldn't breach theirs, plan countermeasures for when a Primordial shows at their door, come up with a way to handle the refugees, both human and Nephilim, check on the Awakened children, contain the Fallen, and save Atropos.
