Bucky doesn't miss the way that Steve twitches and he's by his friend's side before Loki has even finished withdrawing her fingers. He doesn't know what he can do against a shapeshifting god (apparently), but his self-given mission is to protect Steve Rogers, and damn it all he's going to do it.

So he stands over his friend, straight backed, and just glares a silent challenge into Loki's eyes. Loki merely responds with a smirk, and a ripple back to blue form now that he no longer needs to touch mortal skin.

"You may let him up, Thor, in the mortal vernacular he was merely calling me attractive. It has been too long since you were on Midgard, you know nothing of their world any longer."

Loki knows more, though mostly through connection to his children who wander far and wide.

"Now, our business is concluded and I am sure you wish to get these mortals off Asgardian soil before Heimdall informs the All-Father of their presence here?"
