Very well. Kylo's reply was simple as he listened to her. Walking around his own room he picked up a comb and brushed it through his long hair, slicking it back similarly to a photograph he had seen. People would probably stare given his hair was so long, but he wasn't about to cut it all for one day to another world.
He then left his room and crossed through the apartment space toward Heather's door, knocking once to signal his arrival. Some days he was not sure why they simply did not share a home and a bed. Other days he reminded himself he was volatile and she would leave him sooner or later. He was toxic. She shouldn't even be with him. He only wanted to watch the world burn.
