Working for SHIELD had prepared
Stephanie Triggs for a lot of things. One of those things was not an alien attack on New York City led by an Asgardian god. Of course, she had known of Thor's existence what with the whole incident in New Mexico, but she didn't exactly anticipate on his adopted brother sending an alien army into Manhattan. Things had been eventful thus far, and it was only Tuesday. She didn't know how she landed the job of interrogating Thor's psychotic brother, but she wasn't going to argue with Fury or Coulson when they asked her to do something.
If she thought that an alien attack on New York was unexpected, she certainly didn't expect the Asgardian to react the way that she did when she walked into the room. What had once been a cool, stern expression was replaced briefly with one of sadness followed shortly after with hurt and slight anger. She tried her best not to show that she'd been caught off guard as she approached the glass cell that the god had been placed in recently. "No, actually I don't, because last time I checked I haven't died before." She said, crossing her arms. "I think you have me confused with someone else, buddy. My name isn't Sigyn. It's been Stephanie Triggs for twenty-seven years, and I'm pretty sure that's all it's ever been. I'm also pretty sure we've never met before."
For as long as Thor could understand what a soulmark was, he'd longed to find his soulmate. He spent centuries hoping that he would come across the girl whose soulmark bore his name, but he hadn't thus far. Frigga had seen them meet, though, no matter how hard Thor tried to convince her, she would not tell him when he was finally to meet the girl he was destined to be with. All his mother told him was that destiny would bring them together when the time was right. He already knew that he loved her though, he could only hope that she loved him just as he did her.
When he came to Midgard upon discovering his brother's insane plan, his soulmate was honestly the last thing on his mind. Loki had pulled plenty of stunts before, but this was something different entirely. He knew that his brother disliked Misgardians and found them weak, but this was definitely a low, even for him. As he fought to keep the monsters his brother sent to destroy the city, he and the other Avengers were trying their hardest to figure out how to put a stop to this madness completely. Son of Coul had assured him that the agent they sent in to interrogate his brother was one of SHIELD's best, and he was going to take the man's word for it. Thor had known Son of Coul long enough to know that he was someone that could be trusted.
