As Wanda spoke her mind, Loki listened. Not 'Tom', the alter-ego that was plotting her downfall... but Loki, god of mischief. He didn't touch his food, he only sat with his hands folded in front of him, silent. Here was somebody sympathetic.
"You're a very open-minded woman," Loki said, silently.
He'd sired many children over the ages, but only gave birth to one, and as such Sleipnir always held a spot dear and close to his heart. He thought of his connection to Sleipnir, then of Wanda's love for her sons, and he felt a stabbing pain in his heart, the effect of which was clearly visible upon his face. For that moment, he felt a pang of guilt for what he was doing to Wanda. But the wheels were already in motion. It wouldn't matter anyway, if he revealed himself to her now; she would immediately know what sort of monster he was.
