Loki heard his mother reference her hope that he was a gentleman, but he didn't stick around to hear anything more than that. He was not nervous about leaving Natasha alone with his mother - on the contrary, if she were to be as careful and pleasant as he knew she could be, her speaking with his mother for an extended period would do well in swaying some of Frigga's concern for him. He wanted his mother's love - not her eagle's eye. A distraction from him would suit him well.

He returned with a very stiff vodka concoction, which he handed to Natasha, before picking up his own that he had left balanced on the arm of his chair. He would prefer to sit, truly - he was bone weary - but now that he was up, he would not sit again until his mother, or Natasha, chose to do so. He did not let any of his show on his face, of course, as he stood next to Frigga.
