I think Crescent legitimately cares about our well-being, since she told our mom she wants to see us smile. She has an agenda, but to me it seems like that agenda is keeping us out of all this drama (she also said not to involve ourselves with them), like a parent telling a child "How many times have I told you not to play near the woods?"
Speaking of Ren, when we meet Reina idk why we didn't just tell her that Ren joined Team Xen instead of saying we don't know where he is. I would've told her everything about his reaction to the Goldenleaf situation and his decision to join them. (I also would've told Amaria and Jenner about the shipnapping instead of letting them think we overslept)
And speaking of Madame X, she said she's saved us "every time" because we're important...that really makes me wonder who she is, because the masked swordswoman we've been shown tried to do the exact opposite of saving us at Blacksteeple.
