Lisa was shocked to see Luna's number appear on her phone. She had not heard from Ian and she only knew that he was out of the country thanks to her contact within the Lee mansion. She answered the phone hesitantly, she had not properly spoken to Luna in almost three years, and she feared something bad had happened. After a few minutes, the pair ended the call.
The conversation was pleasant, but Lisa read too deeply into its meaning. Luna had basically called to check on Lisa, but in Lisa's mind Ian instructed Luna to call and check in on her. Luna even bad mouthed her brother for being 'communicationally challenged'. If Ian had not asked Luna to call, then why would she? This was the only explanation Lisa could come up with. Her friendship with Luna did not end well, and Lisa thought that Luna would not call out of the blue without being asked to do so. She could not have been more wrong.
