Best solution is probably to rely on SQLAlchemy relationship features to fetch them. If you emit a "joined" relationship the comments for the posts loaded in current page will automatically be loaded with the blogs.
About accessing the paginated data, it is accessible inside the before_render hook, just apply a @before_render decorator before the @paginate decorator so it gets executed after pagination.
