I believe Bitch when she says she doesn’t care about the test(s). Yes, she heavily indicated at the end of 11a that she was intrigued and wanted to see what the tests were all about, but there’s been a significantly different attitude from her since then. She doesn’t seem to actually want to join the Nine.
Which has some implications if the Slaughterhouse Nine lose the game the intended way. They were to take a volunteer, but none of the nominees actually want to join. Not even the other likely option, Hookwolf. So what do the Nine do if noone steps forward?
I’m not sure the game will get to that point, though. I doubt the Nine will win the game, but I suspect their defeat / staving-off won’t be through the game.
Most notably, I suspect that if Jack dies (which can happen if I’m right about Theo), the Nine will break apart. That way, the “Slaughterhouse Nine” will be over, but six or seven powerful psychopaths will still be loose in the city to be dealt with individually in the future, possibly clashing against each other too.
