Loki was very deeply asleep. He had his arm across his forehead. It looked like he hadn't slept well in days. Which was true since he barely could sleep well in prison.
He buried under the covers more, he was crying in his sleep. He was dreaming about his mother. Losing her had truely upset him and her death was bothering him, he wished he had been there to keep her safe from harm. It felt like his fault.
