"So... All I have to do is apologize?"
"You have to be serious about it as well as stop your creepy ass antics. Gideon already found out about most of it and admitted to just excusing it, probably because he was afraid that you would hurt him"
Amias had told Kaiden everything earlier regarding what Gideon felt about their situation. And he even gave a few extra notes on what Gideon might have felt uncomfortable with. It was several key factors that Kaiden needed to understand.
"You need to understand Gideon's personal space, you can't always stick close to him and you shouldn't really force him even if you're the prince. But I'm not saying that you should avoid him altogether like what you're doing right now. I can tell Gideon got bothered by it"
Amias even wanted to add the "even felt guilty when he shouldn't" but they should talk about it with one another since it is no longer his area to pry in.
