[Before reaching the caves, Yuuki spots him while within one of the shops. She appears noticeably different. While she had chopped her hair short in Marina even before her disappearance last time, her natural hair had never been cut, and as such it's incredibly long. While she's managed to pull it back into a pony tail, it naturally hangs past her hips.]
Nico-kun! [She lifts her hand up in a wave. While it may be difficult to tell her from her daughter apart-- not knowing which one suddenly acquired a much longer length of hair, her voice and demeanor probably give her away.]
I'm glad to see you. I'm trying to make sure that everyone made it over.
