“No,” he said quietly, but not a firmly as he would have liked. He did not want to fight with her at all, but he could not turn around. There was no possible way she had gotten her clothes from wherever she had hidden them and put them on already. Loki had mostly avoided looking at her the whole time. It was intentional. He didn't want his resolve to break. She was doing something to him and he didn't like it. Last time his capacity to restrain himself broke he ended up kissing her. He didn't know what would happen next time.
He didn't trust that it wasn't going to escalate. Obviously it escalated enough if she was already standing there, in his house, in his bedroom, wrapped in a blanket from his bed after and she attempted to sneak-seduced him -assumingly, after he'd crawled into bed for the night. And he didn't trust that he wouldn't have taken advantage of that opportunity if it had gotten to that point. He didn't trust himself.
“But that has nothing to do with whether or not I like you, Sig,” Loki said and then stood, adjusted the tuck on the blanket on his waist and without looking or even facing her, moved to the table that held the necklace and the candlestick, grabbing his bag from the floor and started emptying it. Maybe if he kept his hands busy he wouldn't think of the fact that she was wrapped up in his blanket. Though... he could clearly see now that it was missing from the bed. That did not help him at all. “I have never said I didn't like you.”
