Huh? Of course he could. The fact that the story team hadn't thought of Kraata at the time we saw the infected Rahi saga doesn't mean that in-story the Kraata didn't exist during that saga. But it also doesn't mean that powers exhibited in 2001 are automatically kraata powers. You can't explain something written in 2001 via concepts invented in 2003 until 2003. Wrong. We already knew that the Kanohi were infected in 2001, we just didn't know how they were infected. Also wrong, and also not Cheesy's logic. You stretch his logic from "you can't explain something with a concept until you have this concept" to "you can't write prequels". See above.
