Actually, I move that Chi n' I vote Rasei. If nothing else, the role explains Blaire's actions and claims well. Meanwhile, while I understand not wanting to blow a limited use role while you're uncertain, the get Rasei was pseudo investigator, and having even one more result at a time like this would be INVALUABLE, why not use it right away and see if you can't spot a scummy role, or have some way to prove/disprove claims?
As for having the same role, I could actually see that. Hope many times have there been duplicate roles on the Maf and Town, and soon as Town investigator finds it they immediately out the obvious Maf? Could be Five playing with those expectations.
Although...
Blaire. Why were you claiming proper acted on you last night, hence your result?
