About Whitenight, one thing to remember is that once you know about his nature, he completely stops pretending, you have the revelation once and then, that's it, WhiteNight is in the place and he's not hiding.
Even when he is the Plague Doctor, he doesn't so much lie as not tell everything and let your imagination do the rest.
His blessings are genuine, they just do more than the first thing you can see, a thing that the giant clock ticking everytime you get a new blessing makes very clear very fast.
The way to deal with him is actually pretty straightforward in LobCorp too, send someone who is powerful and experienced enough to survive him and don't ignore him, that's it.
Hell, even his favorite work is a good thing for us right now! He prefers Attachment work! The one where you talk and have emotional attachment with the Abnormality in some way, where you cover their social needs.
And that is not even talking about what he can offer X in particular, namely, real advices for her ascension. He is a fellow pinnacle, the one most likely to talk, and that matters.
Out of all the proposed abnormalities presented for X, he is also the one with the best minions in the unlikely case we can manage to obtain some for this raid. Nothing There has none, and we are not sending Kyoko and them in a fight together without first having a long, long discussion with the both of them. CENSORED has lots of them, but they are incredibly prone to collateral, in fact, they are completely indiscriminate. Apocalypse Bird once again have none, plus Apocalypse bird being almost as indiscriminate as CENSORED minions if we obtained direct help from him.
For all those voting birbs, we are not going in the fight alone, and the birbs are bad at team playing, WhiteNight, on the other hand, is all about team playing and having minions servants friends.
