As time went by, Carl's friendship with Adam grew closer and stronger, which meant that Carl could finally trust Adam fully after telling him about Carl's Instinct. However, although Carl trusted him, Carl couldn't stop thinking about what Adam might act if he knew the dark truth behind all of this. Would Adam be disgusted to learn about Carl's past? Or would he feel sorry for them?
In the end, Carl decided to hold back on telling Adam anything until the time is right. There will be plenty of opportunities to tell him eventually. Right now Carl is just happy that he got to know Adam as a friend. The thought alone is enough reason for Carl to be content with that.
But there's one thing that still bothers Carl... Iris.
