These single buildups are getting irritating for me. They wasted the entire episode on nothing. Now Horikita is sick? Really? They could have played this from the beginning and not wait for the last few episodes. I think Ibuki stole the card for Ayanokoji. I think she has a crush on him now. Or it could be very good acting.

Either way this episode felt wasted in many areas and chose not to progress. I suspect the panty thief is a girl whom planted the panties. Probably better to wait till next week as I think now they're going to take multiple episodes to clear up the bullshit they started in the last 4 episodes. When they could have dealt with each one or even a couple in each episode rather than drop everything halfway and continue on in future episodes. Laziness from the company? Makes no sense to me to progress in this manner.
