For a few moments, Thor doesn't react to the press of his brother's lips to his forehead, nor Loki's arms when they fold around him. They should; his brother has never been especially affectionate to anyone but their mother, even when the two of them were boys. This uncharacteristic physical display of kindness should be enough to rip Thor from where he is, but it doesn't.

Not immediately.

But when it does, he wraps his arms around his brother and pulls him him close. He rests the top of his face against the top of Loki's shoulder and for once, doesn't say anything.
