"Riot At Xavier's" is a four-part storyline that ran from New X-Men #135-138 (2003). It was written by Grant Morrison and features artist Frank Quitely's last work on the title. The story centers on an original character of Morrison's, the teenage mutant Quentin Quire. According to Morrison, the storyline was inspired by a playground riot he witnessed in his youth.
Frank Quitely and Grant Morrison worked together on "Riot at Xavier's".
Although Frank Quitely and Grant Morrison both worked on the series, there is nothing to suggest that they worked on it at the same time or even knew one another. The system is assuming that they must have worked together because one of them wrote it and the other worked on it but this is a false assumption.
