Hibito reminisces about Brian, who was something of a mentor to him. Checking the back of the figure, Hibito finds a picture of a young Brian with his brother, realising Brian left the figure there so both brothers would eventually stand on the moon together. The oxygen reserves in Hibito's suit soon runs out, putting Hibito through pain as he gasps for oxygen before almost losing consciousness. Just then, the oxygen producing drone named after Brian arrives on the scene, allowing Hibito to obtain some oxygen in the very nick of time. (thetvdb.com)
