Thanks to centuries of training and experience, Loki was genuinely ambidextrous, not favoring one side or the other. Thanks to being both confident and a good liar, he had no obvious tension. "I'm on the fourth floor, you're on the second." Not exactly neighbors, but good enough.

Someone from his past, good: he'd be looking for allies. Clear piles of guilt, less good: self-destruction was very inviting at times like that. "There are a few people here like that for me." Past and future. Mostly just Stark, at present, though there was some evidence that including Illyana on that list was a good idea. "So he broke the mirror, did he? Better that than you, I'd say." Though Loki more than suspected that it wouldn't have gone very well for the mirror-smasher. Piles of guilt or not, there were instincts there.
