The Stealth Check

You hear footsteps walking around in the dark room. Can I ask mud for a rock? Do you have a rock? I always have rocks. Please give me the rock. No, these are not throwing rocks. Everyone go ahead and roll me stealth checks one more time. Never more. Goddammit Seven Five, seven, two. Snap one. The guards really pick up the pace. They both come around from the south and the north and they point at you guys and yell and the whole room resets. Is there something we're not thinking of to make this work because we are not being good? If it's a simulation, we could just kill the guards stealthily, right
