She wasn't the only one. I'd guess more than half of them will not have done the task. Saying "you were the only one not doing it" is a way to lure her into eventually doing the task even though she initially decided against it by building up "imaginary peer pressure". And even better: if she has second thoughts and decides to do it, she just gave them a nice argumentative path to "decide" against her later anyway - after all, she did hesitate at first "to fully live up to her potential"...
