Terminator: TSCC - The 4th Spider

The Terminator who killed three of the four Spiders is still out there 
along with Cromartie and the fourth member of the human team.  Will 
these folks show up or are they as written off as the Terminator in the 
bunker.

Speaking of that Terminator, if Cromartie could dismantle a safe door, 
why couldn't that one eventually break out of a bunker?

Last observation:  All the male Terminators get beat up pretty quit, 
flesh is fragile, but Cameron takes a beating and just gets cuts and 
scratches.  ***ism?
