Familiar feelings
Aragorn was confused, confused about something he didn't hold possible to be confused about. He was wondering, thinking, doubting about his love for the one he had always loved most of anything and a new feeling he felt for an unfamiliar woman, who had entered his life only shortly ago. This new feeling however, also felt nearly familiar to something he had felt before. Something he endured when he was near or even far away from his beloved Arwen.
Still, it seemed impossible to Aragorn that he could now feel almost the same for Éowyn, who he had only met just a few days ago. Soon he knew he would have to choose between them. However, deep inside something told him that he already knew the answer. The only question was now how to tell her. Until then he could just dream of everything that were his precious memories and what might even be a precious future with his love.
