@Mewples She wouldn't do that, as immoral as she is, she still puts the sect first, and he's an essential asset now. He's way more useful as a cultivator than a honeypot, and she knows this and would leave it alone.
They could always just go the route of 'yeah we had this one dude for a while, we just introduced him in a really convoluted way so that we could test all of you and also justify his existence and place in the sect without needing to expose info on him'. Qin Xinci already came up with that by herself, so it's not that ridiculous a concept. Also would white his rep clean, since it would mean that he literally had to act like that, so he can stop getting anger points and start getting admiration or respect points
