(Variety Show) The Taetiseo and Jessica & Krystal

HEY, i need some help :P At the end of the taetiseo (ep 8) there were parts of seohyun training at the gym. I've had watched the entire 8 eps and  i dont remember seeing seohyun at the gym. Maybe i forgot (ep 1,2 and 6 in october i think). 

And Jessica & Krystal show is the behind the scenes available? If yes, where.

Thank you all. English is not my first language xD
