Nathaniel is now considered one of the leaders of the Wardens at Skyhold. There are meetings with Alistair and Teren, and considerations to be made regarding their relationship with the Inquisition, so Nathaniel takes a day or so to notice Anders' change in demeanor. Anders is quieter, almost prickly. Something is clearly bothering him, and so Nathaniel makes it a priority to un-bother him.

They're very nearly alone in the barracks when Nathaniel comes up behind Anders and wraps his arms around his waist.

"I love you."
