Sometimes the battles aren't easy. They get hurt. They use all their aura. They barely make it to Beacon.
Ren knows what it's like to fear for a partner. He knows she is ridiculously strong and she knows how take care of herself. He also knows exactly how many hits take her down.
Nora knows how terrifying it is when her partner fights close range. She knows he is amazingly fast and he knows how to dodge. She also knows how easy it is for him to get knocked out.
Sometimes the battles are too hard. On their bodies. On their auras. On their minds. Sometimes, when Ren is almost asleep, he feels his bed shift. He feels a smaller form next to him. He moves to make room and pulls her close. He hears her breathe and she hears him.
In these moments, they're not okay. But they will be. As long as they're together, they will be.
