Lucy and the twins certainly noticed how Zelda suddenly went back to being that clueless ditz that they remembered her being, but had yet to connect it with the necklace they had just removed from her.
"Give me the necklace," Lucy ordered Beth. Her cousin handed it over and she put it around her neck for safe keeping.
Suddenly, she felt confused. She looked around like she didn't know where she was.
"Lucy?" Beth asked.
"Are you okay?" Christine asked.
"Like, where am I? Who are you?" she asked, talking like an airhead.
The twins turned towards Zelda.
"What did you do to her?" Beth demanded.
