Just as she successfully completes an endothermic reaction test but before she has finished the system, the power dies completely; she realizes to her growing horror that in her excitement over the message, she completely forgot about saving power. There are no more batteries left either. Without power the station will eventually become an icy tomb, and neither can she finish the blaster: either way means death. As Mei tries to think of a way to restore power-just enough for her work station-Snowball recognizes that there is one source of power left: himself. Not knowing, or even caring about, whether Meihe will be able to recharge him ever again, he plugs into the room's charging port and completely drains his own batteries. Mei notices the power restoring, shuttingbut her renewed hope quickly turns to shock when she finds out why this is happening just as Snowball shuts down.

Sometime after setting out from the Ecopoint in the cloudless day, Snowball wakes up and Mei tells him "Rise and shine, Snowball. We're on our way!"
