Loki & Sif
"Warriors must learn how to take weather conditions into account. Someone complained, but then my troops learned how to work in shield formation and use spears in the mud." This was mostly true, though once the lightning had started, the lesson had necessarily come to an end. But Sif was not inclined to gossip, and she knew as well as any what Loki was getting at. She had known Thor in their youth too.
Instead of taking Loki's bait, Sif changed the subject on Loki. "How fares the work on your current project?" She would not say 'the Bifrost' in company, but she was interested in the project and its success, and not merely because she wanted to travel back and forth between Tonsberg and New York more easily.
