Thetis however remained calm, and for that reason Achilles did not move. His hand moved away and he opened his mouth to speak, but he had nothing arrogant to throw back. Unlike the rest of the world, Thetis could make him do anything.
While he still spoke nothing, his eyes said everything. She was comparing him to another, and that was not something she had done before.
