Pam Wallin wants you to know one thing - she will gladly pay back every dime she wrongfully pocketed in expenses - plus interest. I believe her. I believe she couldn't write that cheque fast enough.
There's something missing. It's the creaking noise from Pam's knees as she supplicates herself, pleading for mercy. It's not the money, well not any more, for Pam. It's the ruination she fears, real "end of the line" reputational Armageddon. That, and of course, the prospect of wracking up a criminal conviction or two in the process. She wants somebody to take her off the hook.
She reminds me of this scene, the end of Tessio from The Godfather.
