Imma do a scan of the video.
At some point near the end ~(10P-E), Joe is swinging his paws around with a pen in it.
Since there were several camera angles available to the varied outlets, there will be a spot where Joe removes that pen from his sleeve or places it in his sleeve for safe-keeping.
Later, tho, because I know it doesn’t exist.
No way he had a pen strapped to his wrist under his sleeve. I think the ballpoint pen conspirators just want it to be something other than a cheating/medical device. Why, I have no idea.
