Peleus should have known what it felt like to have an Olympian's eyes on him. They tended to loom like a rain cloud over one's head even when they didn't need the rain. He flipped his head back laughing and actually enjoying his wife's company.
As they took turns with their cue stick they ended up flirting and laughing more than actually playing the game. The hothead Olympian took his seat at the bar letting his jealous mind twist and turn in thoughts of how he could destroy their happiness because he wasn't happy himself.
