I'm relatively certain he's not talking to you with those ambient comments. He's talking to Kagha. He's not supposed to still be in your camp, for some reason he stays there after the party. If you go to the Druid temple, he's standing there saying those same lines to Kagha.
Yeah this. He's going through lines for his scolding of Kagha sequence. Funnily enough this only happens when Kagha lives, if Arabella's parents dab on her he is silent for the entire party.
