Sil, Chucky and Fex were carted away by some of the staff. They would be briefed on their lesson plan and schedule and everything they needed to cover for the semester as students and teachers.
The meeting that Quinn, Peter and Helen were to attend was one between the higher up staff of the group. Of course, Sam could have requested at least Fex to be a higher staff member but had completely forgotten. Not that it mattered much anyway. As a teacher, he would have plenty of freedom to see Quinn whenever he wished, just not to be in on the big meetings between others.
As soon as Quinn arrived, Oscar was escorting Quinn and his group personally down to the banquet hall where the other higher military staff were waiting. The reason Oscar was waiting for Quinn was because in reality, these two carried the same rank. Of course he would be treating Quinn better compared to the rest of the Head Generals and he would have done the same if Owen had arrived as well.
