The steel door slid shut behind them with a heavy thud.
Liam looked around.
Another corridor. Wider than the last one. Walls made of brushed steel. Riveted panels running along the edges. But this hallway had doors. Five of them. Spaced evenly along the left side. Each one had a small window. Reinforced glass. Thick enough that Liam could see the distortion in it.
Lighting was different here. Not as harsh. Softer. Almost dim. Air smelled like bleach mixed with something chemical that made Liam's nose itch slightly.
He rubbed his finger. The one they'd pricked. Blood had stopped but the spot still stung.
"What was that for?" he asked.
Elena glanced at him. Kept walking. "You were injected with an antibody serum."
Liam frowned. "Why?"
She gestured upward with her chin. "See those vents?"
Liam looked up. Small grates in the ceiling. Evenly spaced. Air flowing through them.
He could hear the faint hum of ventilation.
