Peter rocked back on his heels, his shadow springing up from the ground to make a seat for him, and he pulled Claire into his lap as he sat, holding tight and rocking gently with her in his arms. Despite the need to try, he didn't attempt to calm her, to use his powers to make her feel anything but what she felt. He couldn't bring himself to force anything upon her - she needed to get these emotions out, and in her own way. If that meant holding her until nightfall so that she could cry it all out, he was more than ready to do so.
As he relaxed into position, letting her feel his calm, another emotion filtered into his perception. He knew the source immediately. Nothing in his hold or his breathing betrayed the knowledge. Peter opened the link between their minds again and merely pressed gently at the grip Nathan was holding on his end. Nothing more than that, just to let Nathan know that Peter sensed him, and was comforted by his presence.
