After a good, but difficult conversation with Harry, Elaine set out for the Summer court, in search of her younger self. She had just come face to face with the consequences of her past choices in a very real way, and she wanted Ela to know that things could be different for her. She also wanted get to Ela before Justin did, and make sure the girl would never have to face him alone again the way that she had, and Harry had.
She had a few ideas where Elaine might be hiding. It was just a process of elimination. Every place she checked, she reached out with her magical senses, and called out with the spell that she and Harry had created in order to speak to one another privately, mind-to-mind. She simply recalled herself at that age, and invoked her own Name. Elaine Lilian Mallory.
