The Prompt: Whichever path he chose would ruin someone’s life

 Sam looked between the cells. His heart ached. “Only one?” Whichever path he chose would ruin someone’s life.
The matron walked past again. “Have you made a decision?”
Noise echoed through the hallway. Sam cringed. “Now quite. How do you choose just one?”
She smiled. “It’s hard. I’d take them all home if I could.”
He sighed. “I’ll take the German Shepherd.”
She nodded. “Good choice. Gunner only has one day left. You’ll save his life.”
“And the lab?”
“Shooter stands a great chance of getting out of here.”
Gunner grinned as if he knew he’d just been saved.
