Shelter (слэш)

Loki was shopping with Thor across Midgard when his Seiðr called to him that Tony had entered his apartment back in New York. In all the time he'd known Tony, despite having a key to his apartment, Tony had never entered unannounced, and never when he wasn't there himself. That was concerning enough on its own, but when Tony failed to answer his call, Loki returned back to his apartment only to find Tony in the middle of a panic attack.
