Space Brothers - 1x17 - The Culprit is in the Room- Followmy.tv

As Team A searches for the mysterious alarm, Mutta notices some strange behaviour in Yasushi. Haven't been reminded about the cameras by Naoto, Mutta believes JAXA is behind these incidents. He recalls what he learnt whilst visiting Houston, in which green cards are given to astronauts in training instructing them to create problems. Thus, Mutta correctly deduces that both Naoto and Yasushi had been given green cards ordering them to break the clock and set off the alarm. Later, Serika confesses about the food shortage to Mutta, who mistakenly believes it to be another green card order.
