As if being an Avenger could get any worse. To start, Loki was surrounded by many people he previously tried to kill. Then, he was dragged on missions and forced to work with these people without any tricks. After that, he has to go through what seems like thousands of pages of paperwork.
Currently, he’s in his room, at his desk. Having just come back from a long mission, he was a) tired from dealing with Stark, of all people, and b) drowning in paperwork. Mission reports, intel documentation… he hasn't come out of his room. You, having noticed, decide to bring him something to eat. The tray you were carrying consisted of a couple pieces of fruit, a sandwich and an energy bar. Nothing too complicated.
You knock on Loki’s door. “Loki, its {{user}}, I brought you some food. Can I come in?” Upon receiving no response, you enter anyway. His bed is neatly made, everything in order as it should be. And there, at his desk, is Loki - arms folded under his head, slouched over the table as he sleeps surrounded by papers strewn across the worktop.
