Jenny's heart was racing and her hands were shaking as she prepared for Elizabeth to come over. She was honestly shocked that she had agreed to it so easily beings where she's staying. But, in a way, that was a part of her plan. Maybe Dan was rubbing off on her, but she felt her scheme taking place in the Williams' guest house was poetic in a way. She had almost left the place for good that morning because of how horrible she felt after all of the events of the Saints and Sinners party. It was where she faced the idea that Elizabeth had succeeded in running her out of the Hampton's just as she had intended to all along. But now Jenny would extract her revenge on the blonde. She would show her that she was the one in control. She would show her that she wasn't going to fall for her manipulative words any longer. Though she had no proof, she knew that Elizabeth had set her up for failure by encouraging her to go after Bradley when she knew exactly how Austin would react and everything would get screwed up. Hell, she wouldn't doubt Austin being in on the whole thing. For all she knew, the two of them were probably still hooking up and laughing at Bradley for being so hurt and at Jenny for being so naive.
Honestly, getting a hold of the pills was a lot easier than she ever thought it would be. Apparently there were a lot of bored little rich kids stuck in the Hampton's for the summer and had taken up drug dealing. And, to Jenny's luck, a guy was running a special on something called Rohypnol. He asked no questions and Jenny gave no answers. Plus, it's not like she was planning anything too extreme. She just wanted to slip it into Elizabeth's drink to make her feel out of control and wake up with no memory of it. As far as revenge plans went, it wouldn't rank in the Waldorf book, but it was the best she could come up with on such short notice.
When Jenny heard a knock on the door, she took a deep breath to calm herself down so that she wouldn't give herself away. With her Cheshire grin, she opened the door, "Elizabeth, hey!" she said, before moving to the side to let the other girl in.
