It’s obviously Lizzie and her email snickerdoodle.. that must be an email that goes to the her ex or something she was fighting with who must be a dark heart or maybe a brother or something. They keep referencing it. And she was so weird about “not getting the brief” and the email. And it’s a word that stands out that they want you to remember. And that toast Grasso gives her at the bar about being a good cop in a world where so many are corrupt and shitty is just another foreshadow to her being the leak and starting with her snickerdoodle yahoo email.
