Robert didn't say anything at first, just looked at her, brows furrowing slightly when she talked about being dead but not really and then she dropped the bomb. It was a good thing he was sober. Of course, if he hadn't been, Lyanna would already be inside, drink in hand and... well, this was better for both of them.
"Lyanna," he reiterated. Now that he knew, it was so obvious. Ned's little sister, alive, standing in front of him. And there was no doubt about who the dead 'she' was. Ned and Robert had celebrated the demise of the Martell bitch not too long ago.
"Oh god, Lyanna! I..." A tentative smile touched his lips as he became more animated again and stepped aside.
"Come in, please. I'm sorry, I... I didn't know. Ned never told me... Oh, Lyanna." A soft laugh escaped him when he pulled her into a warm embrace. "It's good to see you."
