Nathan observed Loki carefully.
From his legend, he could conclude three things about Loki. First, Loki created mischief just because he wanted to. It could be out of boredom, but in the end, he caused it out of his will.
Sometimes, he did it without thinking about the consequences to the surroundings. However, it was true that a lot of his mischief ended up in the gods benefiting from him.
Back then, Loki cut Sif's golden hair and nearly lost his own head. At that time, Thor caught Loki and threatened to break every bone in his body unless he secured a replacement.
In the end, Loki visited the dwarves, who crafted new living golden hair for Sif. But it didn't stop there. He ended up bringing back Odin's spear, Gungnir.
Loki mocked the dwarf and bet his own head that the dwarves couldn't craft treasures to rival them.
