“Rivaled only by ‘Locke taught me a new trick,’” added Galdo.
And from Red Seas Under Red Skies:
“What? How dare I contemplate what you were going to do to me? You self-righteous strutting cock, I’ll–”
“What?” shouted Jean.
“I’ll throw myself at you, and you’ll beat the shit out of me,” said Locke. “And then you’ll feel awful! How about that, huh?”
