For reasons of Sougo's shipping fantasies! :3
[Lacus has been in the library more than is typical, research for her planned philosophy class a high priority for now. If she's honest, there's an additional reason today. As much as she enjoys meeting people and greeting old friends, with each influx of new inmates comes the fear of familiar faces that might arrive yet not remember her. Neil and Allen and others that she's mourned.]
[Her face shows no grief, however. That is a private thing to her, and she sees fit, just now, to keep it close to her heart.]
[Seeing Sasha's familiar shock of lovely hair is a welcome sight, despite that they did not know each other so well. Sougo holds Sasha in high regard, and thus Lacus holds her so as well. That alone is enough reason to know her better, but there is one other interesting reason.]
