Azula begins to expect the girl—Lin. Every day, a few hours after her midday meal, she would arrive, staying longer and longer each day. She doesn't always come, although Azula certainly doesn't hate it when she does.
Azula never speaks to the girl; in fact, she'd be barely get a word in, even if she was inclined to speak.
She could try and lie to herself, say it mattered not whether the girl came, but regardless how she spun it, there is one small, undeniable truth.
It is nice to know she isn't completely forgotten.
