She felt it the moment the new arrival came through.
Frigga was a seer by nature. Those in this time might call her psychic, but it wasn't accurate. Her visions weren't exact moments of time. She saw bits and pieces, feelings more than actions. It had always bothered her that she couldn't truly stop what was coming, only brace herself for how it would make her feel. In that moment, she felt...unsettled. Something wasn't right.
When they were young boys, she had placed magical links on both of her children. It was vital to her to know where they were and when they were in danger. All these centuries later, those links had faded and she now depended on her own gifts and her pure maternal instinct. And both of those things were telling her one of her children was in danger.
But that was impossible. Because Loki wasn't here. And the energy radiating towards her didn't feel like his. It felt...off, somehow. Wrong.
Frigga didn't consider herself investigative. That was for Mr. Stark and Dr. Banner and young Mr. Parker. But in that moment, she had questions and she needed answers.
Her outer appearance was calm and relaxed, but internally she was absolutely buzzing with confusion and excitement and maybe even just a bit of fear. Odin would be ashamed, surely. Still, she entered the lobby in time to see a familiar-but-not blur of green magic. And thousands of years of practice and learning were more than enough to tell her the magic involved was not exactly defensive.
Lifting her chin, she studied the new arrival. "I would ask that you not wield that quite so freely around here. There are innocents housed here who have no defenses against your attack." And Frigga had sworn long ago to die all over again defending them if it came to it. "Are you new here?"
