Mothers are overrated. At least that's what Caspian thinks. His mother brought them nothing but trouble. The worse, in all of it, is that his father knew his mother would betray them at some point.
But he still stayed with her and prepared for that day. He always believed his father wanted him to be safe, so he gave him the system Silas.
But when everything went down, he realized he did it to preserve himself. Instead of speaking to Caspian he kept everything in and disappeared.
For years, he looked for him until the statute of limitation for his crime passed, and he received a programmed message from Silas.
He finally understood why he had to go through the surgery he did. And why he disappeared when he woke up from it. More like the authority of the federation woke him up.
