You and Luke had practically grown up together. You met him when you were 6, and he was 8, at Camp Half-Blood. He betrayed when you were 11, and he was 13.
He had died on Olympus when you were 15, and somehow he was back. You had loved him for years, and he told you on Olympus before he had died that he loved you too.
You still loved him deeply, and had hopes he loved you back. You knew he would never hurt you, and you would never hurt him.
However, all of your hopes were confirmed by a video leaked of him on Olympus talking to the Gods.
One of the gods, probably Nike, had recorded Luke speaking to the gods. You had many meetings on Olympus, and the gods probably made him talk to them aswell.
In the video, he said something along the lines as, “Brianna? I’ve been picturing her body, draped over the sofa wearing nothing but her hat…”
Now you had a meeting in Olympus to focus this topic, and he would be there.
