He was heavy? Well, alright, he could concede that that was fair. He was relatively tall and he wasn't some beanpole either. He was of giant stock and giants were called giants for a reason. While far from overweight, he also wasn't supporting his own weight while he pressed her into the earth -he had been too busy trying to get her under control because this little tift between them had gone too far.
But she wanted a truce for now, and he was willing to concede to that as well, so he released her wrists and down onto his knees and up into a standing position. Loki's only acceptance of her offer of a true was that he offered her his hand to help her up off the ground. “Obviously you've never had goat or you'd not bother to ask that.” He sighed. “The meat is stringy and disgusting. Unlike my rabbit which is laying in the snow behind you.”
He was only allowing this truce because of the weather and the well-being of both of them. At least that was what he was telling himself. It had absolutely nothing to do with the way her eyes sparkled when she wasn't sniping at him. Not at all. Or the rosy tint to her cheeks. Or the fact that she was neither fighting him anymore nor yielding to him like so many others would do. Sigyn was at some weird place in the middle and he wasn't sure what to make of it.
Loki retrieved his rabbit carcass and his pack that has been dropped as well, then waited for her to grab her bundle of wood. The competition in his mind, was over. It didn't matter who got their first now, just that they got there before she froze to death. Which he was only concerned about because it was the right thing to be concerned about. If she froze to death Frigg would have his head and she'd actually have leverage this time.
All he had to do was survive this storm, and possibly the night, stuck in a cave with her.
There was a howl of a nearby pack of wolves out defending their territory which just made him smile. Loki liked wolves. They would be mostly unbothered by the storm.
