Loki heard it in Thor's voice. The hurt caused by his sharp words. There was a part of him that wanted to apologize, a sudden knee jerk reaction he wasn't expecting. He rarely did that. He'd done far, far worse things to his brother over their lifetimes. But the reality of his death might have been creeping in to the corners of his mind, a small part of him trying to rationalize what Thor went through in the aftermath. He might have been an asshole, but deep down, Loki did possess a heart. The ability to empathize. He just had a talent at ignoring it too.
He was quiet as Thor showed him the food he had brought, the ghost of a smirk on Loki's face at the offering. Thoughtful. It was quite an adorable trait of his brother that he secretly appreciated. "I do hope," he said quietly, looking up to meet his brother's eyes, "There is at least one statue in my honor in this new home. It would be such a shame for Asgard to forget such a choice physique." The words were certainly said in much lighter tone, nearly teasing, in the wake of his anger.
