I can see some inconsistencies going on here. Sig would have only shown up [i]after[/i] Cora was healed, so he won't see the burns. And Yahtzee was good up to the point he separated Cora and Phil from Will, when there's actually a lot less space going on here. They're almost right beside him, and Cora is currently torn between staying to diffuse the situation with Sig, and going back into the cave to console Thema.
