Loki should have known better, for several reasons. One, though a party was a decent place to stir up trouble, it was also full of drunken idiots who could not necessarily be relied upon to do anything he wanted them to. Two, it was just full of mortals period, which was always unsavory. And three, if there was one place on Midgard where Thor was likely to end up, it was a party. And so here Loki was, having been in disguise as a random mortal, minding his own business, when he was suddenly set upon by the last person on any realm he wished to see.
Despite his indignation at Thor’s unwanted embrace, Loki was surprised that Thor was actually discussing him. Thinking he was doing so to a random mortal, of course, for Thor would never say any of that to Loki’s face. And though he might have been interested to hear the rest of what Thor had to say about him in a flattering light, he was much more irritated at being unceremoniously assaulted.
“While I would love to hear more of this terribly maudlin speech, I would much rather have you release me at once, brother,” Loki hissed, letting his disguise drop, “I was trying to have an enjoyable evening, I’ll have you know. How in all the Nine Realms did you have to end up here?”
Thor’s grip on the poor unsuspecting Midgardian was, as it tended to be when Thor draped an arm around another person while drunk, rather heavy and not very easy to get out from under. While normally the thunder god would have the consideration of lightening his “embrace” for whosoever he happened to rest his arm on, when he was drunk, well, he had no filter and very little consideration for others, at least when it took the finer muscle coordination or thought.
Drunk as he was, when the Midgardian that Thor had his arm draped around transformed into Loki, Thor found himself grasping helplessly for some semblance of an idea, thought, something, that would make that make sense. Because surely his brother was dead. The rest of the Avengers had told him time and time again. Unless it was from the “snap,” once someone was dead, there was no going and bringing them back.
So Thor just squinted at Loki for a moment. “I must say,” he said after a moment, hugging the unfortunate Midgardian closer so he could whisper his alcohol-scented breath into his ear. “I seem to be drunker than I thought, for now you appear to be my brother!” He laughed, a little uncomfortably, because it was sad, and he didn’t want to see his brother’s face because it made him more sad. “Do you know the last words I said to him, new friend?” he said, leaning his head on the fellow’s head.
