Okay, so I got the bone and the pomegranate seeds as directed in order to get into Mt. Orion. I used the bone to get the dog to move. However, now when Rhen talks to the old lady about planting, the old lady asks if Rhen wants something planted and she says, "No." Am I missing something really obvious here?? Why doesn't Rhen just give the woman the seeds to be planted?!
