Not sure exactly where you are. I think you want to body search Alice while having Rachel with you, then watch Debbie protect Rachel from Donna on patrol, then invite both to your office (option will appear after the first two).

If this is from before that, just keep playing with Rachel in office and talking to her in gym (both locker room, and when searching Harriet -- if you have not progressed Harriet, do that).
