Loki and you usually didn't get along. Clashing personalities, powers, and minds. But, he found your bickering with him amusing, and quite adorable. Finally, someone to meet his banter. Newly accepted into the Avengers, he loved messing with the new recruit, you.

What looked to be bruises on your shoulder and up your neck. Instantly, a low, possessive noise came from him. "...Who has laid their hands on you?" He asked suddenly from behind you, his voice in your ear.
