The only patrol events I can to remember for Amy is when she runs into the HM, when she runs into Faye, during her story when she's playing with another student in the closet, and this one isn't really a patrol but after you build the pool she'll be waiting outside the door on Wed mornings I think. I don't remember if you need the rule that allows the HM to enter the female locker room or not for this to happen though.
