In the fight between "Pops" and the young T-800, Sarah Connor shoots the young T-800 in chest. This suggests that, in order to restore the young T-800, parts in the chest area have to be repaired or replaced. But when the T-1000 enters the factory, it drops the mimetic polyalloy (liquid metal) into its eye, where it is absorbed into its head. How does it repair the big hole created by the sniper shot?
Also, when the reactivated young T-800 starts fighting with Kyle Resse, we don't see any visible damage to the internal robot's chest. Where did the damage go?
