for peace of mind you need to help robinfur, first talk to him, give him the poppy seeds, talk to him and accept helping him, meet him at the medicine den nests at night, turn into a med cat apprentice by talking to lunarclaw then breezestar, heal 10 cats and go to the cold stone at brambleclan, after that tell robinfur and go to sleep one or two times, you will get a dream, just look for the firestar shadows, then talk to robinfur again after that and bam, peace of mind. u can also be his mate after all that
