It isn't. [In this instance, anyway. Lacus is aware that Neil was here yesterday and between everything else she's trying not to think about how afraid she was to see him. She doesn't know whether she was more afraid that he wouldn't remember her, or that he would.]
[For Sougo though, he had nothing like that to fear, and a day, a week, months wouldn't be enough. Lacus would do anything to give his sister back to him now.] And it isn't fair. I'm so sorry, Sougo.
