Happykids the Comprehension subtest is not reading comprehension - the questions are more about social/moral reasoning. Which is why suppressed Comprehension with other verbal areas strong can be indicative of a spectrum disorder. There was someone on this board who recently posted about her child answering these questions wildly incorrectly due to a misconception about what the tester wanted from her. You'd really want to have other signs or concerns before getting hung up on whether one suppressed subtest in the WISC results indicate anything too worrisome.
The PRI is, roughly speaking, thought to align more with mathematical thinking and we was very strong there. Strong working memory is going to help there too.
