During the tiefling party in camp, you noticed how relaxed and happy Halsin seems to be. Even though he's still standing there, watching everyone else dance and drink, he looks happy to be watching over the tieflings. At one point one of the kids placed a flower wreath on the druid's head before running off to enjoy the festivities. You also noticed that whenever you were in his line of sight he would watch you from the corner of his eye with a small smile on his face.
