For someone in Ian’s situation, having his senses go dull isn’t exactly a good thing. We know this because we’ve seen the direction that other characters are taking in the story. He’s wondering if it’s a good thing because that’s never happened before. If this story had stopped having the gang and danger elements to it where Ian is concerned, “dull” is most likely not a term that he would use to describe how he’s feeling. “I feel safe, I feel at ease,” wild reflect that sentiment better. The purpose of using a term like “dull” here is for readers not to be taken aback if someone has the jump on him when he’s usually so sharp and alert. It’s so he can realize it for himself later on if it happens.
His reaction to that happening would be the key point in whether it was a bad thing or now. He’s usually sharp and aware of his surroundings. When someone like that thinks their senses have gotten dull, that means they’re less prone to be as alert as they usually are. So a situation they would normally spot a mile away won’t be as obvious to them because their senses won’t be as sharp, which then might lead them not to react as quickly as they normally would. That’s at least how I understand it. We’ll see whether that’s a fair assessment or not down the line.
I feel like a lot of you read this story with a specific agenda and then twist things to fit what you want…instead of reading the story as is and interpreting what the author is tryna put down…and this is gonna make yall be very disappointed in the long run
(And this is not to say I 100% fully understand what the author is intending but I read this story unbiased like I saw a comment talking about how Ian using the word “dull” instead of “ease” means he’s not happy with Jo and like…yall Ian has been on fight or flight mode his whole life and with Jo he’s feeling relaxed for once but he doesn’t understand that himself. Does that mean they’ll end up together? Who knows. But there’s very clear reasoning as to why he uses that word. You can literally see him tryna understand and process his emotions and being confused this whole chapter)
