Back at the day when Marge had the idea, she decided to include everyone and tell her plan to everyone properly. She gathered them around her before she revealed her plan."We disguise the amulet as something else and try using it".
"How would that work"? Oliver asked him. And thus she laid out the perfect plan for themselves. She decided to possess the man who had the documents with himself so that she could get her to sign it. She knew that even if Veronica figured out somehow that the man was actually being possessed, with a room full of people, she would probably be careful of her next step.
Chloe finally found someone to possess and come out of the washroom when she did. It was hard enough to wait there all alone, especially with the fear of Ecthra. She wasn't sure but there was a chance that Ecthra was not along with Veronica anymore. With her being a ghost it was easily possible for him to attack her.
