I copy-pasted this from another comment in case y’all are wondering what just happened:
1. Cain needs Aaron (the doctor) to treat his heart-wound (let’s call it that). He gave the compass cross necklace to Sid to locate Aaron.
2. Sid gave it to some crazy guy who beheaded one of Aaron's clones. That’s why Sid thinks Aaron is dead.
3. Aaron, now aware that he is a target, looked for Cain to offer his services in exchange for protection against Satan. He, along with his red headed friend who is also running away from Satan, went to Cain’s house.
4. Then Sid came to report to Cain that Aaron was dead. But when he gets there, Aaron was very much alive. He still tells Cain that the doctor (referring to Aaron) was dead. This way, Sid can call out to Aaron as an impostor or something like that.
5. In the last chapter 32, Aaron was able to piece together why he was attacked and that Sid was the traitor. Aaron's deciding his next step to convince Cain to get his trust.
How much time passed between chapter 36 and 37?
