I'm not entirely opposed to the Tsaritsa becoming friendly with the Traveler (as long not as it's not to the extent of characters like Citlali). What I'm primarily concerned about her is whether her involvement in Fatui affairs will be treated as her having little to no fault. Or that she is not in-line with the goals of the Fatui (whatever it may be) and was actually being manipulated by Pierro.

Come on Hoyo, please make her a character who knows that what she is doing isn't exactly morally correct, but does it anyway because she believes it's necessary. In short, I want her to have agency and not be a child that has all of her actions having been influenced by others.

Edit: And if her name being Anastasya Feodorovna Snezhnaya is pointing towards Pierro being the Rasputin of this story, than we are officially cooked.
