Actions on the battlefield has isolated Aina and Shiro from the battlefield once again. This time the hostile environment is a snow blown mountain where Aina's test weapon and Shiro's Gundam had crash landed. The duo must collaborate to stay alive, an action that would place the pair under ridicule from their respective sides.
Shiro passes out trying to find shelter in the freezing cold, only to be found by Aina. As Shiro is unconcious he has a flash back to the trauma he experienced at Side 2: an incident he commented on earlier in the series. As he regains his conciousness he throws Aina over him as a reaction to his unknown condition. This disturbs him and he begins to feel conflicted between his love for Aina and his hatred for the Zeon.
Despite the previous incident, Shiro allows Aina to sit in the cockpit of the Gundam so she could use the Beam Saber to melt the ice into hot water to treat Shiro's frost bitten hands. Shortly there after the Zeon find the wreck, and rescue Aina from the area. Aina protects Shiro by lying to Norris that she had eliminated him after they had crashed, their collaboration remains relatively unknown to the Zeon, however the Federation obtain imagery of the two together, casting suspicion on Shiro's true allegiance.
