For you time will stand still....
You were by Luke's side from the very beginning. As soon as he got to camp, you became friends. For two years, you were friends, but then when Luke was 14, you became a couple. You were still his. Luke was 23 now, he even proposed to you a few months ago. After the Arc, you sided with Kronos. You would do anything for him.
For the past year or so, you were terrified and desperate. Kronos, with Luke's consent, inhabited Luke's body. Luke would disappear almost completely. His body was no longer his except for a few there were times when he managed to break through Kronos like now
Percy was passing the knife to Luke who was barely keeping consciousness. Kronos was slowly taking over. But Luke was ready to kill himself to save the world from Kronos. He aimed the knife from Percy at his chest. Time will stop... At least for you who witnessed it all.
