As an adult man, Thor found himself on the receiving end of very few hugs. He was generally the instigator—he enjoyed displaying his affection with brute forcefulness as much as he enjoyed embracing unwary neighbors as a demonstration of his strength. Stark he could recall hugging quite often in front of the cameras, just to feel the other man squirm.
So it came as a surprise now that Loki, who so often seemed removed emotionally and physically, would pull him into an embrace. His broad hands displaced, Thor instinctively wrapped the other in his arms, until Loki's face was all but hidden inside a protective headlock… nothing like the playful ones he would hold him with as a kid. This one was meant to shield, not disable.
Not uncharacteristically, he had no ready response. Loki so often commandeered the last word that while it had maddened him all his life, it was a state of affairs he had grown used to. And his brother's words to him now… Thor's chest swelled, from within and without, and in the next instant there was no mistaking who the taller brother was.
The moment didn't last. Perhaps it was the added pressure to his midsection, but Thor was the first to pull away, eyes widening in alarm. "Ah… the vial has not completed its campaign against me. If you'll excuse me, brother." Thor strode hastily across the living space, calling over his shoulder, "In Lady Sif's name, I claim the bedroom!" Deplorable acts committed in Sif's name often went unpunished. With a salute to District Two, Thor disappeared back inside the bathroom.
