That single pleading word killed him inside. So much so that he winced when she said it the first time. Sigyn was begging him, a position he never wanted her in. It wasn't something he ever anticipated her having to do. Loki looked at his wife again, a deep crippling sadness evident in his eyes. It all pained him, more to see the look on her face and know that she was grappling for any bit of hope she could find and clinging to it. It was paining her too, and that just added to that.
Maybe... maybe he didn't deserve comforts, but Sigyn did. She didn't need to suffer. If she was going to resign herself to his fate, the least he could do was try to make it more bearable for his wife. “Sig,” he said quietly in apology. Sorry really wasn't in his vocabulary, but he owed at least a nugget of apology to her.
Then he paused and though. What could she use that would make this better for her? A blanket, which could double as a wrap for her. And if someone came to see them, as unlikely as that was since he was pretty sure they were left there to rot, she could easily disguise it as a cloak. An apple, she needed an apple from Idun. There were creases on her face from stress and exhaustion. This was aging her. Though he wasn't sure how she could get that. That would involve going to Asgard. He'd suggest it, though. His wife was brilliant, he'd always said so. She'd think of something.
A water bladder. She would need water. Maybe some food.
Finally, he took a deep breath and exhaled loudly. Defeat. Loki was defeated. If the goal of the Aesir was to break his spirit, they had succeeded. “A blanket,” he said finally. “You'll want a blanket. You can wear it like a cloak to avoid suspicion.” He sighed again. “And you'll probably want to wash up and change your clothes before you come back. And eat. You can get a water bladder and some food to store here for yourself.
“And I'm not sure how... But you should find a way to get one of Idun's apples.”
