Mary heard a sucking noise behind her. She turned back and screamed. The mosquito was sucking up the pool of it's blood. If it had taken the growth potion, then the potion would still be in its blood. She stood motionless as the mosquito stretched to 20 feet long and was completely stuck in the hallway, and sounds alerted Mary that it was still growing and would soon be massive enough to burst out of the hall. She would have to do something before it got that large.
