Looking for dramione talking through protean charmed galleons
All I remember is that Hermione is in the horcrux tent with Harry and Ron and they have one galleon. Draco is at shell cottage at some point and also has a galleon. They talk a lot late at night when Hermione has watch. At some point Bill Weasley confronts Draco because he had a galleon too and saw some of their conversation and they have a sort of heart to heart.
I do not remember much else from the fic. I thought maybe it could be "The Disappearances of Draco Malfoy" or "Oops! I joined the good guys" but I couldn't find the scenes I'm looking for in those but maybe I missed it?
