Yes and as I stated I have done all the the parts up to that, there are no option to talk with Kate other that she goes to bed because Claire is in the room next door.You need to rent a room, then talk to kate
Also part 7 in the WT states you can talk with Thomas about the blackmail, there are no option for that either.
Not before evening, during evening, at night, after the Kate serving segment, at no point do the option show.
