St George, the whole thing is a conundrum. 🤔 If he did something easily proven to be reprehensible, it shouldn't be hard to get rid of him. Unless it is some dumb question of ego: that they can't admit that the process may allow flawed characters onto the GB. Which then could cast doubt on any other GB member. And we couldn't possibly have that, could we!? 🙄
The other possibility is one that has already been suggested, that TM3 has enough knowledge about where the bodies are buried, that it is worth the GB's while to protect him and cover for him. If that's what is going on, the smoking gun must be enormous! 😱
