Idun had not been aiming for a smile that implied murderous intent. If she had realized that was the way Bragi was interpreting it, well, maybe that would've changed a great deal about this interaction. She wasn't pleased with this god, but Idun didn't hate him. She didn't hate anyone. But she was young and she could be stubborn, and it was that stubbornness that was holding back the forgiveness she usually offered so easily. Knowing that Bragi thought such terrible things of her would have brought her to her knees, figuratively speaking. Being a bit unpleasant was one thing, but making a stranger believe she would rather push him from the tree than spend time with him was just...mean.
Idun completely disliked things that were mean.
It was a shame, honestly, that Bragi didn't bring any of this to her attention. He smiled, and Idun pursed her lips. "Give me one?" she asked. Her eyebrows made a slow, arched path up, leaving a tiny set of wrinkles between them. What was this god on about? "I'm very partial to my own name. I don't think you'll manage to find a nickname I'll willingly take, I'm afraid." Idun didn't like that she was curious to hear what he came up with. Even making a pointed effort to stay miffed, she was curious about the god in her tree. It was just so natural, and it was such a delightfully odd thing to suggest to a goddess refusing to share her name. Most gods seemed to prefer growling. Bragi liked to talk. Idun loved talking.
But she was being stubborn. She was holding onto the distant memory of her feathered friend. And when she noticed a change in Bragi's expression, she was fairly certain he was coming to understand that as well.
Except his words were both confusing and intriguing, and Idun wasn't really able to toss a little sarcasm his way, because she was curious. This was starting to get annoying. Didn't he understand that she wanted to be annoyed with him? Why couldn't he just leave her to her grumpiness and call it a day? No, he had to ask if she'd heard a story Idun had not heard. There were plenty of stories she didn't know. Stories she wanted to know. Especially if they had to do with trees she loved to climb. "I'm not really from around here, so your certainty is a bit wasted. What happened here?"
She tried not to look interested, but she'd used up all her effort maintaining her annoyance. Idun's expression was undeniably friendlier now that she wanted to hear his story, and there was no going back from that, stubborn as she might be.
