Loki was grateful for the embrace both for the comfort aspect of it and simply because it helped to ground him a bit more in the moment. His head was still swimming and having Thor hug him like he was gave him a chance to close his eyes and just take a breath, allowing the ache in his head to dull somewhat.

As much as he had lashed out at his brother over the years he had never truly hated Thor. All his the feelings he had of not being good enough, of never being a good son stemmed solely from their father and how he had treated them growing up. The favoritism had been obvious, even to a young child, and it had made it's mark on Loki early on.

Need to check on mother. Need to know she's alright.

He finally responds after a long moment of nothing, having opened his eyes when he felt Thor let go of his hands and he'd simply stared down for a few minutes afterwards.

But their mother was the one thing that kept him hanging on, outside of Thor. Plus he'd promised to go back with his brother.
