I think I get it, so another way to interrupt “relevant” information could be seen as knowing what needs to be known or what needs to be done to achieve victory. The know light classes could know more than that but it would take more research and concentration and they would have to look for it rather than simply knowing it.

Think about Rose- She didn’t see Jasprose coming, and she had a breakdown because of it, something she had not seen happened so immediately she thought, it had to be irrelevant, right? Meanwhile, back at the beginning of her adventure, she was tearing down everything just to get Information about SBURB. As she stopped her active search for knowledge, she began trusting her Light Powers more, so when something unexpected happens, it catches her absolutely off-guard, which plays into her confidence problems.
