Idun watched as Thor angled himself away, turning to the fire with the marked determination of the heartbroken. He didn't want to be seen, and Idun could not blame him for that. How would she react if she had a different husband, a husband who wasn't loyal to her, and he betrayed her? She knew that wasn't Bragi, knew that they filled the other's heart too fully for something like that to ever occur, but in this hypothetical life of hers, would she react any differently? Would she face her guest and tip her chin defiantly as tears streamed down her face? No, she wouldn't. She'd turn away too.
"It's okay," she told him softly, reassuringly. Idun wasn't trying to force anything out of him. Her goal wasn't to get him talking, or change his perspective, or anything even remotely similar. Idun just wanted to be there for him. If he didn't have the words right now, that was fine. "I can be pleasant enough for the both of us," she added, though the lightness she tried to fill the words with seemed to fall short of humor. That was fine, though. She really doubted it would be that simple to turn Thor's mood around.
If he wanted quiet, that was fine by Idun as well. She had her hands folded in her lap, but looking around the cabin, Idun saw a small kettle, and that led her quietly from her chair. She said nothing to Thor, didn't want him questioning her if tending to the fire was bringing him even the smallest degree of emotional distraction. No, as silently as possible, Idun picked it up, judged that it would still function as intended, and then she approached the ruins of the kitchen. Oh, Thor had been there, that was certain, but Idun knew what she was looking for, and like most kitchens, there was always something to find to brew into a tea.
She filled the kettle with a chunk of snow, and only then did she approach the fire again, placing the kettle where it rightly belonged in the hearth. And then, still without a word, Idun returned to her chair, watching the way tension kept rolling through Thor's shoulders in waves.
The silence was filled with the sound of the fire crackling, and to Idun, that just showed how caring the god was beyond the violence and anger. She had arrived unannounced, interrupting his emotional rainstorm with little regard for his privacy, and he built her a fire anyway. He was good. Thor was good, and this had happened to him anyway, and it broke her heart. And suddenly, she was forced to remember the one piece of information Bragi hadn't offered her, the one thing she had known that might've saved Thor a great deal of heartbreak.
"Loki once told me of their involvement. It was before you were married, and she chose you over him, Thor," Idun sighed softly. This information wasn't going to do any good, but she needed to be honest. He deserved to know what she knew. "That's truly all I ever knew. And I'm sorry for never mentioning it. I don't know if it would have changed anything, but it was terrible of me not to think to to tell you."
