This is kind of explained, more by intimation than anything. Jade knows Luke is a clone, and is worried that if Luke is given this information in his current state, he might lose all hope and thought and become like Ash - or worse than Ash. And Luke didn't help matters by trying to keep secrets from the rest of them, too, by trusting another asshole that knew what he was and didn't tell him anything, either.name_here wrote:Abyss really, really pissed me off with people not telling the main character important things. Mostly because of how much shit they give Luke when he triggers a major disaster by accident because he didn't know that would happen because no one in the party would answer a goddamn question. Apparently purely because they liked feeling smugly superior rather than because there was some actual reason. They could have averted the catastrophe by telling him what they knew about his powers when he asked.
The thing Abyss did well, though, was growing Luke into an actual character. Sure, it took giant catastrophes, but he eventually became a full person.
