Elena had noticed much of the same things as Spencer, and quickly left the cafe, making it seem as casual as possible. As she exited, everyone in the cafè fell down. They weren't dead, she could see that much. They were sleeping. The green gas had obviously been a sleeping gas, yet it wasn't meant for her. Or, in another light. It wasn't meant to put her to sleep, she was meant to notice it. 

Outside was the guyish-girl, and she could tell she had noticed the same thing as her. Just who was she to have noticed that as well? As she turned to ask her a question, poised to flee at the slightest sign of trouble, a woman approached them. Tall, mid aged, with graying hair, yet a pretty personage over all. She was clearly in disguise. ( Sorry for the brevity, I'm a bit rushed at this current time.)
