Mine is the other way. I think he found his old tape. Because remember in the last episode of season 2? He was so infuriated that SC stabbed Bada. He's so determined to kill SC and find the tape. But now in season 3 I feel like there's a sudden switch in the goal. That's why I have a feeling he found his tape and when he inserted it, now he knows things that the current Doha didn't know. Plus remember the reason why SC removed Doha's old tape? It was because he believed only 1 could escape the game. There must be something that happened that led them to believe that.
TL;DR While looking for Bada's tape, Doha found his old tape instead. And when he inserted it, now he knows more things so there's a change in his agenda with Bada
soooo, does anyone else think that doha definitely has bada's tape and is hiding it from him?
