Pepper sleeps soundly, not bothered by Tony's difficulties in doing the same. She never wakes even as he stirs beside her, not even when he watches her slumber in the faint light of the arc bleeding through his shirt before eventually following her. She remains unconscious to it all, just as she does when she rolls on her belly in the wee hours of the night so that her side presses up against him, her body gladly gravitating toward his blissful warmth without consent from her mind.
