Zeke yanked out the pin and tossed it down the stairs. The men shouted at each other, wondering what it was. One of them realized it was a grenade and they panicked. Then Zeke heard a clunk–clunk and realized they had thrown the grenade back. Risking getting shot, he dove for it and threw it back. The men shouted again, louder this time, and then with a bang the grenade went off.
