Sif wasn’t sure what she was supposed to be doing without her powers, without any ability to contribute to the Avengers team. Thor was enjoying his time among the humans, but he still had his powers. He hadn’t been banished and stripped to humanity by Odin for defying his wishes by helping when Loki was trying to rule humanity.
Natasha had helped try to introduce her to proper clothing and ways to do her hair with Earth’s tools. It was different. The fabrics on Asgard were so beautiful, like they’d been made from stars; she was feeling naked without her armor.
It was Bruce who had given her a new hobby: taking pictures. It was helping her to explore the new land, this… New York. It was so that she could see new places, remember them; see people, meet the millions that littered the city streets, parks, subways.
The fascination waned quickly, leaving her alone, lost and defeated.
