I am on mobile so copy / pasting the evidence will be difficult for now so hopefully some helpful frens post links in the comments.

In the video of the "Thumb Drive Hand-off" you see four perpetrators who I will refer to by clothing: Purple (fat white girl), Blue (fat black girl with braids), White (fat black woman with colorful afro), and Childrapist Gambino (rail thin soyboy in leather jacket, CG for short).

Purple is the connection to the source of the thumb drive. She has it from the beginning of the video, and deposits it somewhere behind White. This location is obscured a bit but I suspect she let it casually drop into a bag of sorts hanging off the back of White's chair, or something in that area. However it was done, Purple should be proud of her sleight of hand. Please note during this time that White, Blue, and CB are not moving much at all or doing anything, really.

White is in charge of scanning in boilerplate / partially-filled ballots into the machines. She reaches behind her to grab something, presumably the thumb drive that Purple dropped. She hands it across the table in a manner (not as gratefully as Purple) to Blue. White proceeds to stay very still. Later on, she will scan the same stack of boilerplate ballots three times. I'm guessing each ballot gets its own file with a unique but generic name (like FultonBallot00065 or whatever). So the same stack of ballots will work as they are generically filled out, but many files are needed for CG (explained later).

Blue is the communication hub between perpetrators, as their supervisor (reportedly). She slowly turns around away from White (who is potentially her mother) in an awkward way, glancing around the room for potential prying eyes. She slowly gets up, which isn't abnormal for a hambeast, but it's still awkward and strange, like a teenager trying to move in for an end-of-date kiss but chickening out at the last second. Blue gets up awkwardly, and pretends to stretch or something. She slips the thumb drive into CG's front left pocket. CG is also pretending to stretch at this time, angling his hips towards Blue's outstretched hand. Blue, if a supervisor, also potentially may assign seating arrangements, getting these 4 close together.

CG's role is to assign each boilerplate ballot an identity to tie them to a "citizen". That is what's on the thumb drive - created, crafted, found, or otherwise illegally obtained voter information. As far as I know, there is currently no video evidence of this. But that's what makes logical sense when you know White is scanning in multiple boilerplate ballots to be presumably registered in a database, which CG will inevitably have access to for reference. He needs to be identified immediately.
