One is an extended promo and the second one is a short promo but seems to have a hidden scene flash for a split second and will that we have added below.
NOTE: No new scenes really in the promos, but they aired during Dancing with the Stars so it focuses on the quadrangle plot a little more and includes scenes from the season.
Thanks to Yoshio for the promo.
Thanks to Solid for the heads up and Carlost for the promo
