It took him a while to come back to reality - to realise he was in a moving car next to the one man he could honestly say he had a love-hate relationship with. He didn't have the world in the palms of his hands anymore, and he was thousands of years too old to be walking the earth.
"I wasn't drooling," he said quietly, breaking his seemingly self-imposed silence, rubbing his eyes with the back of his hand.
They were still on the highway, which was a good thing, and he didn't think he had missed his target. He wasn't a god anymore - just an old man - but that didn't make him completely useless.
That and Zeus would have probably pulled over and shaken him awake if he saw the man in the picture walking down the road. After all he hadn't told his younger brother anything.
