Showed the break fall, technical standup, flower/pendulum sweep and the arm bar from there. For next time, I have to insist even more on breaking the person's posture with the free leg (under the armpit), and insist on bringing the person's weight on top for the sweep to work.
Had a few very slow rolls in the advanced class, but we only rolled every second round, due to too many people being on the mats.
In black belt class, we worked on Z guard passes : the key is a level change pass with opens up a knee slide. If the hook stays in, go around in either direction, but keep pressure on the person with your hips.
