Linda might not be as outspoken as Caroline and Alexa but she was definitely smart. Her friends have failed which means they would come looking for her.
It all happened in a flash, one moment they were all having fun and the next, all hell was let loose.
She hadn't gone into the basement with the others cause she was given a different assignment - keep Ben busy.
Truthfully, it wasn't a difficult task since the guy was already wasted but he would wake groggily from time to time, asking about his goddess or something? She couldn't exactly tell.
But she was a smart girl, so she kept him distracted and busy until the incident occurred.
She had been the first to escape before anyone else could reach the door.
Linda knew it wasn't a coincidence the house began to quake the moment her friends went to have a bit of fun with the girl.
Something must have gone wrong , something must have happened.
