Sentiment is a defect of the losing side...
Original prompt - two characters and one line: knitmeatardis said: Maybe a bit of crack, but… Loki Laufeyson, Sherlock Holmes, “Sentiment is a defect of the losing side.”
"Sentiment is a defect of the losing side." Loki glared as he pronounced the words, hands clasped behind his back, marching back and forth, his lips pursed.
"Does that mean you won’t play, then?" Sherlock steepled his fingers, smirking slightly, and propped his feet up on the shaky chair that John used to sit in while he balanced his accounts and paid bills. He glanced at the chess board, set up but for Sherlock’s first move: an ivory knight slipped past the row of pawns. Gleaming quietly in the neon light shining through the old and dingy curtains. "Are you afraid of sentiment, Mr. Odinson?"
“Laufeyson,” spat Loki.
"My mistake," purred Sherlock, smiling again. He gestured at the board. "Your move."
Loki narrowed his eyes and turned toward the card table, striding quickly across the room and looking down at the pieces. “This is a foolish battle strategem,” he said. He looked at Sherlock, scoffing. “What kind of army has only two horses?”
Sherlock could not suppress a laugh, and it burst through his lips, his shoulders shaking for a moment.
Loki only glared.
"Oh, I’m sorry," said Sherlock, wiping the tears that formed in the corners of his eyes. "Truly, sir, I’m sorry, but—"
"You’re… ridiculous,” said Loki, leaning on the table with two fists, looming threateningly toward Sherlock.
"And you’re the one who’s trembling with sentiment — with fear," said Sherlock.
Loki said nothing.
"You don’t know how to play, do you?"
Loki glared. “Silly Midgardian game.”
Sherlock grinned, his teeth showing. “So, no?”
Loki yanked the chair out from beneath Sherlock’s feet and sat heavily and quickly in it. He copied Sherlock’s move exactly, with the smooth onyx knight on his side. “Do your worst,” he said.
Sherlock grinned, pushing a pawn forward. “You’ll do better if you don’t glut yourself upon french doughnuts and italian coffees at every meal,” he said.
Loki narrowed his eyes. “How did you—”
Sherlock smiled. “Oh, I always know.”
