Loki lied, plain and simple. He was the God of Lies and it came as naturally as breathing. However, lying to himself was more difficult than anything he ever tried to do. Loki always thought he hated Thor. Well not always, there was a time when he truly loved Thor more dearly than any other on Asgard.
Ever since Loki had found out the truth of his parentage, he had tried harder and harder to not think of Thor as his brother but as an enemy. He put all the hate into his words and tried to convince Thor that he had given up their brotherly relationship for good. Loki honestly believed that he hated Thor, but there were moments where unwanted memories would creep into the crevices of his mind.
Thor had begun to take Loki's advice and move on with his life without him. He cringed as he remembered Thor's rough voice telling him that they were done and should move on with their lives separately. Loki should be throwing a party, right? This is what he wanted, for Thor to hate him like he hated Thor.
It had been 3 days since he had last spoken to Thor. Three long, boring days with absolutely no company at all. Loki was used to Thor rambling on, trying to convince him to do something together or telling him how they were still brothers despite the fact they didn't share the same parents. It had annoyed Loki to no end. The separation was beginning to drive Loki crazy, or crazier, and he was playing the last conversation with Thor he had over and over again.
Why though? Why? Loki hated Thor. They weren't really brothers and Thor didn't truly care for him. So, why did Loki feel like he had been stabbed in his heart with a dagger when he saw Thor with his replacement? Replacement you ask. Well Cade is the one being referred to. He is around the same age as Loki, but was a lot like Thor.
His bro- Thor had been doing everything with Cade lately and though Loki wouldn't admit it aloud, he was extremely jealous. He did everything in his power to stop calling Thor brother, even just to himself, but it was hard; especially when his nightmares came back. Endless nights passed by and the one conclusion Loki could feasibly draw was that maybe he needed his big brother after all.
