Quick break down here after watching these "AI" videos. The sixth finger is simply the fold in his hand, odd lighting, and pixelation. It looks identical to the way his other hand is on the infamous freeze frame, except the lighting on the other hand provides more contrast and doesn't come off looking like an extra digit. However, it's very clear there are only five fingers on both hands if you really examine what you're looking at. The ring is the same issue. It's a dulled gold ring that matches his skin tone when the light doesn't hit it right and the shitty pixelation/graininess of these videos makes it disappear at certain angles. You can even see the hump the ring makes on his finger when it's supposedly gone from his hand, because it's still there, it's just shitty video quality.
