Gate agent put a passenger in seat XB.  When the gate agent boarded the plane to confirm the cabin count with FA B; I discreetly asked her why there was a passenger in XB. She got very befuddled and confused and forgot that she was boarding a [type aircraft]. I told her that at one time I wanted to put a deadheading pilot in XA; but the gate agent informed me that she would have to write me up for doing that so I politely asked passenger to move back to his assigned seat. Because we were ready to close the door I let the passenger sit in XB; but throughout the flight he lifted his mask above his mouth.  He was sniffling and blowing his nose and his mask remained above his mouth.I'm not sure what should be done.  If gate agents have told me they will write me up moving someone to XA; then I suppose this gate agent should be reminded of our policies.
