For those who may not know, season 2 of Tokyo Ghoul (which was titled Tokyo Ghoul root A) was not all canon material. The majority of the season was original anime content. As of this writing there is no information as to whether season 3 will revisit the beginning of the manga or if it just continues from where season 2 left off.
