"I wouldn't worry too much. This is just gonna be a routine extermination," Nick said with a sigh as the car began to slow to a halt. "I've tangled with Goblins before. The only time they were ever a problem was the Hopkinsville Incident, and the upper brass want to make sure that NEVER happens again." Getting out of the car, Nick proceeded to open the trunk and withdrew some items they'd need for the upcoming extermination. Among them, he grabbed a clip-board and a forged U.S. Fish and Wildlife Service badge. He then turned to approach the house, flipping a signal for Thea to turn invisible. If the people in the house proved uncooperative, standard procedure would have Thea possess them to comb their memory and then wipe it once they had the information they needed. 

When he reached the door, Nick gave it a stiff knock that echoed in the darkness of the night. After several moments, a middle aged woman pulled the door open partway. She had a frail build and mousy brown hair pulled back into a bun. Nick smiled as he flashed the badge that he'd tacked to his shirt. 

"Good evening, Miss. Sorry to bother you at this late hour, but I'm with the Fish and Wildlife Service. There was an issue involving an oil spill a few miles south of here and it's causing some of the animals in the area to migrate. We're just running a survey to see if you've noticed anything... unusual in the last few days?" Based on her expression, Nick wasn't altogether sure she was buying his story, but he hoped the official-looking nature of the badge and clipboard could make up for his explanation.
