S2·E20 Suspicion breeds suspicion! The notebook that makes it happen!

Lunchtime during the typical school day obfuscates the anguish wrought upon Kaoru, Shiho, and Aoi due to their leader being away for wartime training as well as Hanae informing Fujiko of Tim and Barrett's current status;in an attempt to forestall their reclamation by Black Phantom, janitorial labor has been decided for the two boys. Fujiko phasing out after an admonition for rigorous vigilance for Tim and Barrett yields to old Obata charging Hanae an important stewardship: a notebook endowed with the psychic power of serendipity. Unfortunately, Obata has two notebooks -- one of which Kyousuke discovered. Hypnotically emulating Minamoto, Kyousuke pollutes the B.A.B.E.L. database and decides to amuse himself by wielding Obata's notebook to compromise the cohesiveness Kaoru and her teammates enjoy. The ensuing series of game theory exhibitions promptly demonstrates that Kaoru, Shiho, and Aoi (along with the adult B.A.B.E.L. personnel) will turn on each other like sharks in a blood-crazed feeding frenzy without Kyousuke's external assistance. Kyousuke's downfall is set in motion when Dr. Sakaki detects his emulation of Minamoto and Momotarou falls out of Kyousuke's pocket.
