Strong, clever and honorable were good qualities to have. Enlil had no lack of faith that even if whoever the child's sire was that his sister was more than capable of instilling such qualities in him herself. She was all those things as well... and much more. They all were, in their own ways. Enki gave way a bit more to flights of fancy, wandered a bit more as his passions took him, which was less of the erotic and more of whatever his interest was that the moment -but he was just as clever and intelligent in his own way. It as a desire to learn and understand. They, the first children of Anu, they all had this and they would pass it on to each generation as best they could.
None of them were dim. Which was why he did not play the fool and pretend he did not catch any inference that Namtar would be that like his father and then after a beat, turned it to Enlil. Like him No. The Lord of Storms was not dim but he was, perhaps, a bit confused as to if he was understanding her correctly this was just being made known to him now. Which was patently obvious in the confused expression that turned toward his sister, taking great care to in no way change how he was holding what was likely his son.
It would now be more important than ever to not harm him. “Me?” He asked, wanting clarification -mostly on why he would not have been told sooner.
But just as soon as he finished speaking, his gaze was drawn back down to the child and everything in him softened and warmed in a way that would have been impossible for anyone outside of his family to notice.
