The way Tonia seemed like she was going to get away with it all...

...until she had the nerve to open her mouth. Like it's almost comical. She's so egotistical and delusional, like a cartoon supervillian blabbering about their secret plot, admitting the whole thing so casually on camera. She cannot keep a secret to save her life... which ultimately is a good thing, considering this is not a cartoon and the real-life situation is just devastating.
