"Yes," he said, trying to keep it rather light even though the truth was that he spent a lot of the time doing labor that she just couldn't on her own. "I try to do that a few times a year. Or more if she sends word somehow." Loki was trying to keep his hands busy. This was really more the sort of conversation he really only had with three other people Only three others knew the situation involving his mother and his asshole father who never actually claimed him in any formal sense. Those three had been Odin, Hoenir and Thor.

Loki did try to laugh, though. "Don't worry, she puts me to work. There's a lot to do, she's by herself and," he sighed and figured why not and just came out with it, "has... some limitations."
