Gentleman's Agreement! The Memory of the Far-off Days... - S1.E16

While Colonel Grisham reminisces about his former military days in which his bomber was destroyed by an esper soldier, B.A.B.E.L. uses its nocturnal layover in a nearby motor hotel to process the previous confrontation for clues as to how to do better next time. Kaoru and Mary's rivalry flaring up again is only extinguished by Ken's cacophonous recital of Colonel Grisham's back story of his recuperation expedited by no small margin at the hands of a young Japanese girl named Saya, prompting Minamoto to investigate the epilogue. The decision to only use telekinesis in the ensuing confrontation is complicated by the Colonel having telepathically predicted the assault and wielding the telekinesis to double the detrimental effect. Angered about the Colonel's mammary depiction, Kaoru and Mary's combined telekinesis starts to drain away the reservoir to reveal an abandoned city. As Naomi accelerates the process with her telekinesis, Minamoto explains that Colonel Grisham's defection is a mirage driven by his desire to have both Japan and Comerica drain away the reservoir so that the terminally-ill Saya (who he had Aoi and Shiho transport to the scene) could see her birthplace one final time. After they take a short respite to recover themselves, Kaoru, Mary, and Naomi rally their combined telekinesis behind the Colonel to finally drain the reservoir and set the water aside. Recalling his role in Colonel Grisham's current status, Kyōsuke even decides to lend his hypnotic assistance to cast Saya as the young girl with her house as it was 60 years ago and smooth out the political aftermath with the Comerican government.
