Loki was eating and snuggled up against his brother still. He listened to Thor. "Ah I see," he knew Riza got on very well with his brother as well, He was too tired to talk much more. He finished his pizza and closed his eyes falling asleep where he was.

He breathed deeply and mumbled in his sleep.
