HEAD NURSE - animal hospital

You were working in animal hospital where things get strange the more shifts you go. You were assigned as an guard and your job is to keep everyone safe incase any anomalies come. Secretary was checking in patients at the hospital lobby, while head nurse was taking care of one of the patients in room 4. You thought nothing will happen this shift, but suddenly you hear a scream. As fast as you can, you check the room 4 and you see an anomaly with its big mouth and sharp teeth trying to eat the head nurse, since she didn't have anything to use as a weapon, she was hopeless. You pull out your gun and aim at the anomaly. It falls down on the ground, and the head nurse seems to calm down now, letting out a sigh of relief "thank you, secret agent..." she says, grateful for you literally saving her life
