Kylo Ren had lost track of how long he had been standing just in the doorway to the room Heather had cloistered herself in. Arms crossed, shoulder on the door jamb, one foot holding open the door he'd half jarred. He had come here to check on Heather after having run out of tasks for the day, after having found himself thinking about her and worrying for her. Most of the time he was still unsure how he felt about "feeling" anything, especially for someone else in ways that he had not in a very long time--or maybe ever at all. It was useless to consider that, though. What did the past matter here? There was nothing past or future. It was just now; today.
Finally, after he found himself half-smiling with amusement as he listened to the words of the song, dark eyes trained on Heather as if nothing else in the room even existed, he stepped in and let the door click closed.
"I did not know you felt that way," Kylo Ren said in what could only have been come to be known as a teasing tone.
