Branwen may have been slightly disappointed that she and Lucy didn't have a chance to talk the night before, but you would never have known - she felt disappointed about most everything these days. But she was curious, and so, after her (disappointing) class, she went up to the dormitory in the hopes that she would meet Lucy there, and when she wasn't, Branwen proceeded to wait. As she had said before - it wasn't like there was anything else for her to do.
When Lucy arrived, Branwen smiled - a genuine sort of smile which was rare in the past week. She repositioned herself on her bed to face Lucy better, and nodded. "I'll never get used to the size of it," she affirmed, before quieting to hear what Lucy had to say.
Branwen raised her eyebrows slightly at Lucy's words, curious and puzzled. She nodded once, to indicate she knew this was a secret and would stay that way. "I promise not to tell a soul."
