Loki does step back because filthy, wet, and muddy pawprints all over his clothes are definitely not the look he's going for today. His hands stay in his pockets as he watches the two of them, expression distant and eyes slightly unfocused.

His mind is definitely elsewhere.

He's thinking of Asgard and its people. How there's an entire timeline of people he's never going to see again, like his brother. His mother. If he does ever see them again, they won't be exactly the same as the ones he left behind.

It makes him wonder what Abby's family is like. If she misses them.

But once Abby has Wagner settled down again Loki approaches once more, taking steps carefully measured as to get the least amount of mud on his boots as possible. "I'll admit, the 'you won't fuck this up' part was not what I expected you to open with."
