Maggie turned around, so she was walking backwards when she heard Nate speak to her on what she was expected to do next. In truth, she didn't like to be bossed around, but due to the situation, she will have to be the follower. Between her and Shaggy, she was the dominant-head of the two: having to remind him at times, put him back on task, and ironically, having to be the youngest, she would drag him like a dog. 

Funny it may sound, but it's like the roles have been switched these past years:  she was the "oldest" now. Giving Nate a confused, dubious expression at his words, she rolled her hazel-colored eyes before walking away to the gang's quarters upstairs. Moving the flashlight side to side, Maggie cautiously shines a light of each door, quietly debating on which one would be her brother. It's easy to track his whereabouts at home, so she did the basics: look at their belongings. If it was Shaggy's, then all she would see is a messy room. 

She indeed found it; clothes scattered all over the place, it looks like someone turned it upside down. Pictures on the wall weren't out of place with his family inside each one, except one with a piece of, what seems to be, paper sticking out from the side. Weird enough? It was sticking out of a picture with a younger version of her and Shaggy, along with a puppy cutting in between them: Scooby. Carefully lifting up the frame, Maggie scanned the design with her flashlight; a stub with a label of 'SPOOKY ISLAND'. It now snapped her mind! "Nate?", she called the young man before running out of the dark room, with the stub in hand, nearly slipping on the clothes on the way out.
