The Rising Dawn: Infection

You and your mom hide under the stairs for 20 minutes until the man comes back. "Hello?" he calls out. He looks all around until he comes to the stairs. He starts to bend over to look under when you shove the knife into his neck. You immediately cover his mouth. He falls lifelessly onto the ground. You rip the bloody knife out from his neck, slitting his throat to make sure he's dead. You take the handcuff keys out from his pocket. You and your mom head upstairs. You see the men sitting on the couch, unaware anything happened.
