Great epsiode...after ep3 it became harder to see where this arc is going to bring us. Initially it started to follow Tatarigoroshi-hen's footsteps, then with the twist that Satoko cosulting the club members. At that point I thought it would've been interesting if it went along that route, but Rika dismissed that as usual.
It's also good that they are picked back up some of the great scenes they have left out in season 1, this time with Kameda and some Soul Brother references. Hopefully they will have an epsiode to do the dessert festival so that we can see the "Club memebers vs. Otaku" scene.
